Real life chemistry
This document provides definitions and examples for various chemistry concepts. It defines matter as anything that has mass and volume, and gives a cell phone as an example. Not matter is defined as things without mass or volume, such as music. Pure substances consist of only one type of particle, like aluminum foil. Elements cannot be separated further, like gold. Compounds are composed of two or more elements with constant composition, such as table salt. Mixtures contain substances not chemically combined, such as Coke. Physical changes alter form or state but not substance, while chemical changes produce new substances, like paper ashes or popcorn.
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.
Physical Properties Of Matter
The document discusses several physical properties of matter including thermal conductivity, state, malleability, ductility, solubility, density, and how density relates to whether an object will float or sink in water.

Characteristic+properties+of+matter
This document discusses characteristic properties of matter. It defines matter as anything that has mass and takes up space, and provides examples of common materials that are considered matter, such as plants, animals, rocks, water, air and oxygen. It explains that characteristic properties help scientists identify different types of matter, as they are unique to each substance and do not change even if the substance changes form. Characteristic properties for matter include physical properties, like state of matter, density and magnetic properties; and chemical properties, like flammability and reactivity with other substances. Identifying characteristic properties allows one to determine what kind of matter one is examining.
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
Matter is anything that has volume and mass. Volume is the amount of space an object occupies and is measured in cubic units like cubic meters (m3) or cubic centimeters (cm3) for solids. Liquids are measured using a graduated cylinder. Mass is the amount of matter in an object and is measured in kilograms (kg), while weight is the measure of gravitational force on an object measured in Newtons. A physical change alters physical properties like state but does not change identity, while a chemical change produces new substances.
Unit 2 Properties of Matter
This document provides an overview of properties of matter. It begins by defining the three states of matter - solids, liquids, and gases. It describes the properties of each state, such as solids having a fixed shape and volume while gases have no fixed shape or volume. The document then discusses physical and chemical properties and changes, defining the difference between physical and chemical changes. It provides examples of each. Density is also covered, defining concepts such as mass, volume, and density and providing practice problems. The document concludes by discussing elements, compounds, and mixtures.
Lecture 2.1- Properties of Matter
This document discusses properties of matter and the different states of matter. It defines extensive and intensive properties, with examples such as mass and volume being extensive as they depend on amount, while hardness is intensive as it depends on the type of matter not amount. The three states of matter are defined as solid, liquid, and gas. Solids have a definite shape and volume, liquids have an indefinite shape but definite volume, and gases fill their container. During physical changes, some properties change but not the composition.
Yaer 4 ppt 1 Matter states properties
Matter is anything that has mass and takes up space. Mass refers to how heavy an object is based on the amount of particles it contains, while volume refers to the space an object occupies. Mass and volume can be measured using tools like balances and measuring cylinders. The properties of matter depend on how closely packed and attracted the particles are - solids have a fixed shape and volume as particles are tightly packed, liquids have a fixed volume but not shape as particles are moderately attached, and gases have no fixed shape or volume as particles are far apart with weak attraction.
Matter physical chemical properties
This document discusses physical and chemical properties and changes of matter. It defines matter as anything that has mass and occupies space, while energy has no mass and occupies no space. Matter is composed of atoms, which are made up of protons, neutrons, and electrons. Pure substances like elements and compounds have a constant composition, while mixtures can have variable compositions and can be either homogeneous or heterogeneous. Physical changes do not alter the chemical makeup of a substance, and involve changes in state, shape, or size. Chemical changes result in new substances forming through reactions that alter chemical compositions. Chemical properties involve reactions, while physical properties can be observed without reactions occurring.
Unit 3 Physical Properties of Matter
This document discusses various physical properties of matter including states of matter, changes between states, and other properties such as density, viscosity, conductivity, malleability, and hardness. It describes the four states of matter - solid, liquid, gas, and plasma - and changes between these states through melting, freezing, vaporization, condensation, sublimation, deposition, and more. Additional sections cover properties like viscosity, conductivity, density, malleability, and the classification of elements.
Matter and material
This document defines matter and materials. It states that matter is anything that occupies space and has mass. There are three states of matter: solid, liquid, and gas. Pure substances like elements and compounds have uniform composition, while mixtures are composed of two or more substances that differ in properties. Mixtures can be heterogeneous, with non-uniform composition, or homogeneous, with uniform composition throughout. The document provides examples of elements, compounds, and mixtures to differentiate pure substances from mixtures.

Transmission of Heat - Daily Life Examples
This document discusses three methods of heat transfer: conduction, convection, and radiation. Conduction involves the transfer of heat through direct contact between objects. Convection refers to the transfer of heat by the circulation of fluids like gases and liquids. Radiation involves the transmission of heat through electromagnetic waves that do not require a medium.
Chemistry in our daily life
Chemistry is present in many aspects of everyday life. Some examples provided in the document include soaps, water, oils, foods, air, and literally every object that can be seen or touched. Soaps are made through a chemical reaction between alkali and fatty acids. Water is a chemical compound made of hydrogen and oxygen that exists in different physical states. Oils come from various sources and are used for things like food, fuel, and manufacturing materials. The document emphasizes that chemistry helps us understand the composition, structure, and changes of all matters in the world around us and underlies many everyday phenomena and products we encounter.
Role of chemistry in every day life
This document discusses the role of chemistry in everyday life. It notes that chemistry is important in areas like food, medicine, diseases, and daily activities. The human body itself is largely composed of chemical compounds - roughly 96% of the human body's mass is made up of just four elements: oxygen, carbon, hydrogen and nitrogen. Chemistry helps in understanding vitamins, supplements, and how drugs can help or harm the body. It also plays a role in medical research to understand diseases on a molecular level.
Ideal Gas Law
An ideal gas is a theoretical gas that follows Boyle's, Charles's, and the ideal gas laws. It is made of particles with negligible volume that exhibit random motion and no intermolecular forces. Real gases deviate from ideal behavior at low temperatures or high pressures due to intermolecular forces or particle volume. The ideal gas law relates pressure, volume, amount of gas, and temperature as PV=nRT.
The Ideal Gas Law
The document discusses the ideal gas law PV=nRT and its application to real gases. It defines the four variables in the equation, describes how the ideal gas law relates these variables, and explains how to derive the gas constant R. While real gases deviate from ideal behavior, the ideal gas law can still adequately describe gases at low pressures and temperatures near room conditions. Two examples are given applying the law to calculate pressure and temperature for gas samples.
Importance of chemistry in daily life
Chemistry plays an essential role in life on Earth. Organisms use chemicals to survive in extreme climates through enzymes that protect membranes. The human body also relies on chemistry, using chemicals to break down food and produce mucus layers that protect organs. While chemicals are necessary for life, they can also pose harm, like stomach acids. Synthetic materials created through chemistry have benefits over natural materials by combining desirable properties without negatives. However, chemical reactions used to make synthetics can also be dangerous, so safety precautions must be followed.
Application of gases
The document discusses gas laws and provides examples of how they apply in everyday life. Boyle's law states that the pressure and volume of a gas are inversely proportional at constant temperature. Examples given include shaking a soda bottle and spraying aerosol cans. Charles' law explains how the volume of a gas increases with temperature. Examples are helium balloons and dented ping pong balls. Gay-Lussac's law says gas pressure rises proportionally with increasing temperature at constant volume, illustrated by firing bullets and burning tires. Avogadro's law concerns the direct relationship between gas volume and number of gas particles. Examples include projectiles, balloons, breathing, and baked goods rising.
Behavior of Gases
Gases have no definite volume and assume the volume of any vessel. The behavior of gases is described by gas laws including Boyle's law, Charles' law, Avogadro's law, and the ideal gas law. Real gases deviate from ideal behavior at high pressures and low temperatures and are better described by equations like van der Waals. Key gas properties include gas formation volume factor, gas compressibility factor, gas viscosity, and gas solubility in oil. Gas formation volume factor relates the volume of gas at reservoir conditions to standard surface conditions.

1) Boyle's law states that the volume of a gas is inversely proportional to its pressure when temperature is kept constant. Charles' law describes the direct relationship between volume and temperature of a gas at constant pressure. Gay-Lussac's law explains that pressure of a gas rises with increasing temperature at constant volume.
2) The combined gas law incorporates Boyle's, Charles's and Gay-Lussac's laws to describe the interrelationships between pressure, volume and temperature for a fixed amount of gas.
3) According to Avogadro's law, equal volumes of gases under same conditions of temperature and pressure contain equal numbers of molecules. Dalton's law states that total pressure of a gas mixture is the sum

This document defines key chemistry terms including matter, elements, compounds, mixtures, states of matter, and physical and chemical changes. It provides examples for each term to illustrate the concepts. Matter is anything that has mass and takes up space, while thoughts are not considered matter. Elements are pure substances made of only one type of particle, while compounds contain two or more elements. Mixtures can be either heterogeneous, with visible components, or homogeneous, appearing uniform. Physical changes alter the form or properties of a substance without changing its chemical makeup, while chemical changes create an entirely new substance.
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.

Physical and chemical property final
There are three main states of matter: solid, liquid, and gas. The temperature at which a solid melts into a liquid is called the melting point, while the temperature at which a liquid boils and turns into a gas is called the boiling point. Water's melting point is 0 degrees Celsius and its boiling point is 100 degrees Celsius. Matter has physical properties like density, volume, and viscosity that can be observed without changing its chemical makeup, as well as chemical properties involving chemical changes and reactions with other substances.
0708_matter.ppt
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.
Matter
The document discusses the properties of matter. It defines matter as anything that has volume and mass. Volume is the amount of space an object occupies, while mass is the amount of matter it contains. The key differences between mass and weight are explained - mass is a measure of the amount of matter and stays constant, while weight varies depending on location as it is the measure of gravitational force on an object. Physical properties can be observed without changing the substance, while chemical properties describe its ability to change into new substances.
Matter Properties And Changes
The document discusses different types of properties of matter including physical, chemical, and biological properties. It defines physical properties as those that can be observed without changing the identity of the substance such as mass, volume, density, state, color, odor, and hardness. Chemical properties describe a substance's ability to change into a new substance with different properties through chemical reactions. Biological properties distinguish living from nonliving things.

Matter, States and Physical Properties.pptx
This document provides an overview of the kinetic molecular model of matter. It describes the three main states of matter - solids, liquids, and gases - in terms of the arrangement, separation, and motion of molecules. In solids, molecules are close together and vibrate in place, giving solids a definite shape and volume. In liquids, molecules move more freely but have a definite volume and take the shape of their container. In gases, molecules move freely in all directions, causing gases to have no definite shape or volume and fill their container. Matter can change states through processes like melting, freezing, boiling, condensation, and sublimation in response to changes in temperature and energy. The properties of each state relate to
Matter
Matter can be summarized as follows:
Matter is anything that occupies space and has mass. It exists in three states - solid, liquid, and gas. Matter changes between these states through processes like fusion, condensation, evaporation, and solidification. Matter can be classified as pure substances or mixtures. Mixtures contain more than one substance and can be separated using methods like evaporation, distillation, filtration, and decantation. Changes to matter can be physical, changing its shape or size, or chemical, changing its composition.
