Phase Changes

Melting

Solid to a Liquid when heat increases

Freezing

Liquid to a Solid when Heat is Decreased

Condensing

Gas to a Liquid when Heat is Decreased

Evaporating

Liquid to a Gas at the Surface of the Liquid

Vaporizing

Liquid to a Gas all throughout the Liquid

Sublimating

Solid to a Gas, skips liquid phase

Two ways to change the state of matter

heat and pressure

Particle change when heat is added

Spread apart and move more

Particle change when heat is taken away

Move closer together and move less
