This document discusses the key physical and chemical properties of matter. It defines matter as anything that has mass and takes up space, and defines key terms like mass, weight, volume, density, states of matter (solid, liquid, gas), freezing point, boiling point, melting point, and compounds. It distinguishes between physical properties, which can be observed without changing the substance's composition, and chemical properties, which involve a substance interacting or reacting to form new substances. Examples of physical properties include hardness, texture, color, odor, taste, and temperature. Chemical properties involve behaviors like flammability, rusting, and reactivity with other substances.
Matter can be described by physical and chemical properties. Matter is capable of undergoing physical and chemical changes based on these properties.

The power point was designed to be like a kiosk information center. We were to pick a subject area and content area of our choice. Mine consisted of second grade science, dealing with the states of matter.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
8. States of MatterStates of Matter
• There are different “states” of matter.
No, not like Texas, Oklahoma, New
Mexico. States of matter are also
known as phases (a physical state of
matter). Elements and compounds can
move from one phase to another phase
when special physical forces are
present.
• Solid
• Liquid
• Gas
10. Boiling pointBoiling point
• The boiling point of an
element or compound
means the temperature
at which the liquid form
of an element or
compound is at
equilibrium with the
gaseous form.
• the boiling point of water
is 100 degrees Celsius.
11. Melting pointMelting point
• The temperatures
at which the solid
form of the
element or
compound is at
equilibrium with
the liquid form.
• Basically the range
at which the solid
changes its state
into a liquid. •The melting point of
water is 0 degrees
Celsius
12. CompoundCompound
• A substance
made of two or
more elements
chemically
combined in a
set ratio.
– Water and salt
are 2 examples
of compounds.
13. All substances have properties…All substances have properties…
Including people!Including people!
Example:
People can be
identified by
their …
Face
(shape,
expressions)
Voice Height Finger
prints
Eye color Hair color Teeth DNA
14. What are properties?
• Matter has observable and measurable
qualities.
• We can use general properties to identify
substances.
• Two basic types of properties of matter:
Physical properties and Chemical
properties:
15. Physical PropertiesPhysical Properties
• Physical properties are used to identify,
describe and classify matter.
– Characteristic of a substance that can be
observed (using your senses) without
changing the substance into something
else.
Hardness Texture Color
Odor Taste Temperature
16. More EXAMPLES -
Physical
• size, shape, freezing point, boiling
point, melting point, magnetism,
viscosity, density, luster and many
more.
– Viscosity - The resistance of a liquid to
flowing.
– Examples:
– Low viscosity-water, rubbing alcohol
– High viscosity-honey
17. Chemical Properties
• Chemical properties are characteristics
involved when a substance interacts
with another substance to change its
chemical make-up.
Flammability Rusting Creating gas
bubbles
Creating a
new chemical
product
Reactivity with
water
pH
