Anything that has mass and volume

Mass

The measure of the amount of matter a substance contains

Volume

The measure of the amount of space a substance takes up

Solid

A state of matter that has a definite shape and a definite volume

Liquid

A state of matter that has a definite volume but no definite shape.

Gas

A state of matter with no definite shape or volume

Melting

The change in state from a solid to a liquid

Freezing

The change of state from a liquid to a solid

Evaporation

The change of a substance from a liquid to a gas

Condensation

The change of state from a gas to a liquid

Sublimation

The change of state directly from a solid to a gas

Deposition

The change of state directly from a gas to solid

Melting Point

The temperature at which a solid becomes a liquid

Freezing Point

The temperature at which a liquid changes into a solid

Boiling Point

The temperature at which a liquid changes to a gas

Condensing Point

The temperature at which a gas changes to a liquid

Solid Particles and Energy

Solid particles are close together and have low energy and movement

Liquid Particles and Energy

Liquid particles have more distance, energy and movement than solid particles

Gas Particles and Energy

Gas particles have more distance, energy and movement than liquid particles

Particle Theory of Matter

A theory that describes the composition and behavior of matter
