Properties and Changes

2. What is Matter? Opposite of energy Has mass and volume
Made up of atoms

3. Mass ( grams or Kilograms)
The amount of matter (atoms) in an object
Measures how hard it is to change the motion of an object ( its inertia)
Measured by a balance

4. Volume ( mL , L, cm3)
The amount of space occupied by an object

5. Properties of Matter
Are traits that describe matter; physical or chemical
Intensive- properties that do not change if the amount of matter changes ( melting point, density)
Extensive-properties that change as the amount of matter changes ( volume, mass, energy)

6. Physical Properties Describe the appearance of matter
Ex: color, texture, shape, mass, state of matter

7. States of Matter Solids- definite shape and volume
Liquids-definite volume, takes the shape of its container
Gases-indefinite shape and volume
Plasma-high temperature charged particles ( atm of the sun)

8. Chemical Properties Describe how matter behaves
Ex: flammable, reactive, oxidizes, corrosive, explosive

9. Physical Changes
Matter only changes appearance; it’s still the same substance
Ex: Dissolving, Phase Changes

10. Phase Changes Melting- solid -> Liquid Freezing-liquid -> solid
Boiling- liquid -> gas
Condensation- gas -> liquid
Sublimation- solid-> gas
Deposition-gas -> solid
+ heat energy
- heat energy

11. Chemical Changes Matter changes into a new substance
Ex: Burning, Cooking, Chemical Reactions

12. Classifying Matter

13. Classifying Matter

14. Some other examples
