Describing matter powerpoint
Matter can exist in three states - solid, liquid, and gas. Examples of solids are ice and diamonds; examples of liquids are water and mercury. Gases include water vapor and oxygen. Characteristic properties like boiling point and melting point are used to identify substances and do not change, even if the substance changes state. Physical changes alter the substance's form through processes like melting or crushing, but do not change its chemical makeup. Chemical changes form new substances through chemical reactions.
Periodic Table of Elements Grade 7 1st Quarter
This document provides instructions for an activity to familiarize students with the periodic table. It asks students to complete a table by identifying the symbols for various elements using their periodic table. It also asks students to identify the group number each element belongs to. The objectives are for students to demonstrate familiarity with the layout of the periodic table, recognize information about elements, and identify element group numbers. Students are directed to write the activity name and date in their notebook before answering questions using their periodic table to identify element symbols and group numbers.
Phase changes
The document discusses the different phases of matter (solid, liquid, gas) and the phase changes between them. When energy is added to a solid, its bonds break and it melts into a liquid where particles can move freely. Adding more energy turns the liquid into a gas where particles move randomly. The phase changes - melting/freezing, vaporization/condensation, sublimation/deposition - describe the changes in particle arrangement that occur when energy is added or removed. Phase changes are classified as endothermic, where energy is absorbed during the change, or exothermic, where energy is released.
States of matter
This document discusses the three states of matter - solids, liquids, and gases. It explains that in solids, particles are tightly packed and vibrating in a fixed position. In liquids, particles are tightly packed but can slide over one another. In gases, particles are very far apart and move freely. The document also discusses physical changes like melting, freezing, boiling, evaporating, and condensing. During these phase changes, heat is either absorbed or released by the matter. Finally, it explains that chemical changes occur when new substances are formed through rearrangement of atoms.
Particle Theory of Matter
The document summarizes the particle theory of matter. It states that all matter is made of small particles that are in constant motion. The attraction between particles determines the state of matter, with solids having the strongest attraction and gases having the weakest. Heating a substance increases its energy and motion by breaking the attractions between particles, causing them to spread farther apart.
Lesson 1 the particle nature of matter
This document provides information about the particle nature of matter. It includes standards and objectives about demonstrating an understanding of the particle nature of matter and its properties. It discusses the key concepts of explaining the properties of solids, liquids, and gases based on how the particles are arranged and move. It also explains physical changes in these states in terms of particle arrangement and motion, and how this can be used to explain processes like melting, freezing, evaporating, and condensing.
Atoms, Element, Molecule and Compound
This document defines and provides examples of atoms, elements, molecules, and compounds. It states that atoms are the basic unit of a chemical element and are made up of protons, neutrons, and electrons. An element is made of only one type of atom, while a molecule forms when two or more atoms bond together, whether of the same or different elements. A compound contains at least two different elements bonded together. It provides examples like water (H2O) as both a molecule and compound since it contains hydrogen and oxygen atoms bonded together.
The properties of matter
This document discusses volume, mass, density, and physical and chemical properties of matter. It provides definitions and examples of:
- Volume is measured by looking at the bottom of the meniscus of liquids.
- Mass is the amount of matter in an object and is constant anywhere, while weight depends on gravity.
- Density describes how compact a substance is and can be used to identify substances and determine if objects float or sink.
- Physical properties like state and solubility can change without changing the identity of the matter. Chemical properties involve chemical reactions that form new substances.

Biotic & Abiotic Factors + Biomes (Grade 7)
Ecology is the study of how organisms interact with each other and their environment. Organisms are affected by biotic factors like other living things as well as abiotic factors like temperature, sunlight, and rocks that are non-living. A biome is a large geographic region defined by the plants and animals living there. There are two main types of biomes - terrestrial biomes like tropical forests, tundras, and deserts, as well as aquatic biomes including freshwater ecosystems like lakes and rivers, and marine ecosystems like coral reefs and oceans. Biomes provide habitat for many interconnected species but are threatened by human impacts like climate change and habitat destruction.

The document also lists common element names and their Latin origins, as well as symbols introduced by these early scientists who helped establish the foundation of modern chemistry.
Chapter 2 notes properties of matter
Everything can be categorized as either energy or matter. There are two types of properties that characterize matter: physical properties, which can be observed without changing the substance, and chemical properties, which are observed when a substance changes. A physical change alters a substance's size, shape, or form but not its composition, while a chemical change creates a new substance with different properties. The law of conservation of matter states that matter is neither created nor destroyed in physical and chemical changes.
Properties of matter
This document defines matter and discusses its properties and changes. It begins by defining matter as anything that occupies space and has mass. Matter's properties are then divided into physical and chemical. Physical properties can be measured without changing the substance's chemical identity, while chemical properties deal with how substances react with one another.
The document goes on to categorize physical properties as either intensive, meaning they do not depend on amount of matter present, or extensive, meaning they do depend on amount. Examples of intensive and extensive properties are given. The three states of matter - solid, liquid, and gas - are described. Physical and chemical changes are then defined, with a chemical change altering the composition of matter.
Lecture 2.1- Properties of Matter
This document discusses the properties and states of matter, describing extensive and intensive properties, and how matter can exist as solids, liquids, or gases depending on how tightly or loosely packed the particles are. Key topics covered include classifying properties as extensive or intensive based on whether they depend on amount of matter, identifying substances based on uniform composition and properties, and explaining the defining characteristics of solids, liquids, and gases in terms of particle motion and arrangement.
Module 2 atom inside out (grade 8)
J.J. Thomson discovered the electron in 1897 through his cathode ray experiment and proposed the "plum pudding" model of the atom in 1904. Later experiments provided evidence that atoms are made of even smaller subatomic particles. In the 1910s, Rutherford discovered the nucleus through his gold foil experiment and proposed a nuclear model of the atom. In 1932, Chadwick discovered the neutron through experiments bombarding beryllium with alpha particles. Atoms are now understood to have a small, dense nucleus containing protons and neutrons, surrounded by electrons in orbit.
Unit 28 - Heat And Temperature
Temperature is a measure of the average kinetic energy of particles, with higher temperatures indicating faster particle motion. There are three main temperature scales: Fahrenheit, Celsius, and Kelvin. Fahrenheit and Celsius are used to measure temperatures experienced in daily life, while Kelvin is used for scientific purposes since it does not have negative values. Heat is transferred between objects through conduction, convection, and radiation. Conduction requires direct contact, convection occurs through fluid movement, and radiation transfers heat via electromagnetic waves.
Subatomic Particles and Isotopes
This document discusses subatomic particles, isotopes, and ions. It defines atoms as the smallest unit of matter that retains chemical properties. Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus. The number of protons determines the element, while the number of neutrons defines the isotope. Ions are formed when atoms gain or lose electrons, becoming positively or negatively charged. Practice problems are provided to calculate subatomic particle numbers for elements, isotopes, and ions.
Nature of matter ppt
The document summarizes key concepts about the nature of matter including:
- Matter is anything that has mass and takes up space. Physical properties like color, size and state can be observed without changing the substance.
- Elements are substances made of only one type of atom. Compounds contain two or more elements chemically bonded together.
- Atoms are the basic building blocks of matter and contain protons, neutrons and electrons. The number of protons determines the element.
Properties of Mixtures and Pure Substances
Matter can be classifies as a pure substance or mixture. They differ based from their properties and arrangement of particles.
Classifications of Matter
This document defines the classification of matter. There are two main categories: pure substances and mixtures. Pure substances include elements, which are made of only one type of atom, and compounds, which are two or more elements chemically bonded together. Mixtures contain two or more pure substances mixed together without chemical bonding. Mixtures can be either heterogeneous, where the parts can be seen, or homogeneous, where the parts cannot be seen. Heterogeneous mixtures are less pure than homogeneous mixtures.
Lesson 3- Synthesis of Elements in the Laboratory.pptx
1) Elements are synthesized in the laboratory through nuclear reactions such as bombarding one element with protons, neutrons, or other light elements. This changes the number of protons and neutrons in the nucleus to create a new element.
2) The first synthetic element was technicium, created in 1937 by bombarding molybdenum with deuterium. Transuranium elements like neptunium, plutonium, and curium were later synthesized by bombarding uranium with neutrons or alpha particles.
3) More recently discovered superheavy elements require bombarding very heavy, scarce elements like berkelium or californium with even heavier projectiles like calcium, and the heaviest

COMETS,ASTEROIDS, AND METEORS
Comets are small icy objects with two tails made of gas and dust that formed over 4.6 billion years ago in the early solar system and have highly elliptical orbits. Asteroids are small rocky or metallic objects that orbit the sun, ranging in size from meters to hundreds of kilometers wide with irregular shapes and cratered surfaces. Meteors are streaks of light seen when meteoroids - space rocks or fragments that can be from comets, asteroids, moons or Mars - enter the Earth's atmosphere. Some meteoroids survive entry and land on Earth's surface as meteorites.
Whats The Matter
Matter is anything that takes up space. Mass is a measurement of how much matter is in an object, and can be measured using a balance by placing unknown objects on the left side. While mass and volume measure an object's matter, weight is affected by gravity and mass is not. Density compares how much mass an object contains relative to its volume, and can be used to compare different objects or substances based on how much matter they contain in a given space.

The document also discusses plasma as the fourth state of matter and its many applications in manufacturing, medicine, and waste processing.
Ch 1 Matter in Our Surroundings Slide show 3.ppt
- Matter exists in solid, liquid, gas, and plasma states and undergoes physical and chemical changes. Physical changes alter a substance's state or form without changing its chemical makeup, while chemical changes create new substances.
- Substances can be elements, compounds, or mixtures. Elements cannot be broken down further, while compounds have a fixed composition and can be decomposed into simpler substances through chemical changes. Mixtures are combinations of substances that are not chemically bonded and have variable compositions.
- Plasma, the fourth state of matter, consists of free-floating ions and electrons. It is created by applying energy to strip electrons from atoms and can be controlled using electric and magnetic fields. Plasma research aids in understanding
Matter and change
The document discusses the key properties and characteristics of matter. It defines matter as anything that has mass and takes up space. It describes the three main states of matter - solids, liquids, and gases - and their properties. It also discusses physical and chemical properties, mixtures and compounds, and how chemical and physical changes can alter matter.

This document discusses the classification and states of matter. It begins by defining matter and classifying it into elements, compounds and mixtures. It then describes the three states of matter - solid, liquid and gas. Physical properties and chemical properties are distinguished. Physical properties can be observed without changing the identity of the substance while chemical properties involve changes to its identity. Common phase changes like melting, boiling, evaporation and condensation are also outlined.
Matter
All matter can undergo physical and chemical changes. A physical change alters the appearance but not the chemical composition, such as water freezing. A chemical change forms new substances with different properties, like reactions with acids or bases. Substances have characteristic intensive properties that identify them and extensive properties that depend on amount.
Chapter 1.2 Matter and its Properties
This document discusses the properties and changes of matter. It defines matter as anything that has mass and takes up space. It distinguishes between physical and chemical properties and changes. Physical changes do not alter the chemical identity of a substance, while chemical changes produce new substances. The three common states of matter are solids, liquids, and gases. Pure substances have a uniform composition and properties, while mixtures maintain the identities of their components but are not uniform throughout.
Matter
There are three main types of changes that matter can undergo: physical changes, chemical changes, and changes in state. A physical change alters the appearance or form of a substance but not its chemical makeup, while a chemical change creates an entirely new substance. The four main states of matter are solids, liquids, gases, and plasma, which differ based on the structure and movement of their molecules or atoms.
Matter
This document discusses physical and chemical changes, states of matter, and properties of matter. It defines physical changes as changes in state without chemical composition changes, and chemical changes as changes that result in new substances. It describes the three common states of matter - solids, liquids, and gases - and some of their distinguishing properties. Plasma is also discussed as the most common form of matter in the universe.

The document discusses the four states of matter: solids, liquids, gases, and plasma. It describes their key properties and how the particles in each state are arranged. Solids have a definite shape and volume, with particles packed tightly together. Liquids take the shape of their container but have a definite volume, with particles loosely packed and flowing around each other. Gases spread out to fill their container without a definite volume, and have freely moving particles. Plasma is similar to gas but with electrically charged particles. The document also explains that adding or removing energy can cause matter to change states, such as melting solids to liquids or evaporating liquids to gases.
1 What Is Chemistry
The document introduces chemistry as the study of matter. Matter is anything that has mass and volume. Mass refers to the amount of matter in an object, while volume refers to the amount of space an object occupies. Atoms are the basic units that make up matter and molecules form when two or more atoms are bonded. Matter can be classified as pure substances or mixtures. Pure substances are either elements or compounds, while mixtures are either homogeneous or heterogeneous. The three common states of matter are solids, liquids, and gases.
Matters
The document discusses the different states of matter and phases. It explains that matter can exist in solid, liquid, gas, and plasma phases. The solid phase occurs when molecules are tightly bound, while the liquid phase allows molecules to flow freely but maintain a shape defined by their container. Gas molecules exhibit random motion and the least intermolecular forces. Plasma is an ionized gas that conducts electricity. The document also briefly discusses Bose-Einstein condensates, an exotic state of matter.
General Chemistry.pptx
This document provides an introduction to general chemistry. It defines chemistry as the study of matter and its transformations. Matter is anything that has mass and occupies space, and can exist in different states such as solid, liquid, gas, and plasma. The document discusses physical and chemical properties of matter, as well as physical and chemical changes. It classifies matter as either pure substances like elements and compounds, or mixtures that are either homogeneous or heterogeneous. The key concepts covered include the states of matter, phase changes, and the classification of matter.
World of matter for class 9
Matter is anything that occupies space and has mass. It is composed of small particles that are in constant motion and hold together through chemical bonds. The amount of empty space between particles determines the state of matter, with solids having the least empty space and gases having the most. Changing the temperature of matter affects the motion and bonding of its particles, allowing it to change states between solid, liquid, and gas through processes like melting, freezing, evaporation, and condensation.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
