What’s the Matter?

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

The End
