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

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

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

24 The End
