1. What’s the Matter?

2. Matter is anything that takes up space and has mass

3. Law of Conservation of Matter
Statement that matter can change from one form to another but can not be created or destroyed

4. Properties
Are characteristics or descriptions that make an object unique to other objects
Two kinds of Properties
Physical
Can be observed or measured without changing the identity of the matter
Chemical
Matter that can change into new matter with different properties

5. Physical Properties Color Luster Size Composition Elasticity
Malleability

6. Physical Properties Volume Density Mass States of matter
Thermal conductivity
Solubility

7. 1. Color and Size
Red Small
Green Medium
Blue Large
Etc.

8. 2. Luster
Ability to reflect light
Shiny metals, glass, mirrors, etc.

9. 3. Composition Refers to what an object is made of Wood Glass Plastic
Cork

10. 4. Elasticity
Refers to how much the object will bend or stretch without breaking and return to its original shape

11. 5. Malleability
Ability of a substance to be rolled or pounded into thin sheets
Ex. Aluminum foil

12. 6. Volume Refers to the amount of space an object occupies
Volume can be found by 2 methods
Measuring
Water displacement

13. 7. Density Refers to the amount of matter in a given space or volume
Density can be found by using the following formula
Density = Mass divided by volume

14. 8. Mass Refers to the amount of matter in an object
Mass can be found by using a triple beam balance scale

15. 9. Weight Refers to the pull of gravity on an object
You can measure the weight of an object by using a spring scale
Mass and weight are not the same thing
Ex. You will weigh less on the moon than on earth because the moons gravity is 1/6 that of the earths

16. 10. States of Matter
Solid
Liquid
Gas
Plasma

17. 11. Solubility
is the ability of a substance to dissolve in another substance
ex. Flavored drink mix dissolves in water

18. 12. Thermal Conductivity
Is the rate at which a substance transfers thermal (heat) energy
Ex. Foam cups do not transfer thermal energy

19. Solids Have a definite size and shape
Can change to a liquid if heat is added known as the melting point
Particles are packed very closely together
Particles can not move only vibrate back and forth

20. Liquids Takes the shape of the container but has a definite volume
Can be changed to a solid at 32 degrees Fahrenheit (freezing point) 0 degrees Celsius
Can be changed to a gas at 212 degrees Fahrenheit (boiling point) This is referred to as evaporation
100 degrees Celsius
Particles are loosely packed together
Shake fast and move around easily .

21. Gas Does not have a definite shape or size
Fills any space that is empty
Particles are very far apart
Particles move freely in all directions

22. Plasma
Plasma
Does not have a definite shape or volume and the particles have broken apart example: lightning, fire, and aurora borealis

23. Chemical Properties Reactivity with Oxygen-forms a new substance
Iron rusts
Nonreactivity with Oxygen- does not react
Chrome bumpers on cars do not rust
Flammability- easily burns
Propane gas burns easily-used in stoves and ovens
Nonflammability- does not burn easily
Aluminum or metal pots to cook in
