How do you Define MatterMatter is Defined by it's properties. The properties of matter are, mass, volume, weight, and density. Mass is the amount of matter in an object. Volume is how much space an object takes up. Weight is the force of gravity on an object, and density is how heavy or light something is for its size.

*Mass: amount of matter in an object*Volume: How much space an object takes up*Weight: the force of gravity*Density: How heavy or light something is for its size

What are the States of MatterThere are three states of matter. Solids, Liquids, and Gases.

SOLIDSIn order for an object to be classified as a solid it must possess these properties. Solids must retain their shape, have the same volume regardless of the contain, and can not be poured.

*Retain their shape*Constant volume*Can not be poured

Key Words: SOLID = FIRM & STABLE

LIQUIDSIn order for an object to be classified as a liquid it must possess these properties. Liquids take the shape of their container, do not of a definite volume, and can be poured.

*Take shape of container*No definite volume*Can be poured

Key Words: LIQUID = FLUID

GASESIn order for an object to be classified as a gas it must possess these properties. Gases fill the volume of their containers, can be poured, and do not have a fixed volume.

*Fill the volume of their container*No fixed volume*Can be poured

Can objects change their state?Yes, objects can change their state of matter by adding or removing heat.

*Can change their state by adding or removing heat*Add Heat:

What happens to the weight if an object changes.

If an object changes it state or breaks apart, the weight of the object does not change, which means the weight stays the same. So, let's look at an example.

Shrinking Styrofoam Cup

Even though the styrofoam cup shrunk in size it's weight did not change. The pressure compressed the tiny air pockets within the cup reducing it's size.

*If an object changes state:*Weight DOES NOT change

What happens when objects are heated and cooled?

When the temperature of a material increases the particles move faster and expand or spread out. When the temperature of a material decreases the particles move slower and contract or shrink.

Examples:

*Increase in temp. particles expand or spread out*Decease in temp. particles contract or shrink*Water Expands when frozen

Key Words: EXPAND = SPREAD OUT CONTRACT = SHRINK
