What’s the Matter?

Matter is anything that takes up space and has mass

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

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

Physical Properties Color Luster Size Composition Elasticity
Malleability

Physical Properties Volume Density Mass States of matter
Thermal conductivity Solubility

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

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

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

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

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

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

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

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

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

10. States of Matter Solid Liquid Gas Plasma

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

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

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

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 .

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

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

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
