Phases of Matter and Energy

The state of matter that has particles close together and vibrating.

• liquid

• solid

• gas

• water

The state of matter where particles are very spread out and moving quickly.

• gas

• liquid

• solid

• Helium

The phase change when a solid becomes a liquid.

• freezing

• sublimation

• melting

• condensation

During a PHASE CHANGE, like freezing, temperature...

• increases.

• decreases.

• does NOT change.

• varies.

The phase change when a liquid becomes a gas.

• melting

• boiling

• sublimation

• evaporation

The phase change when a gas becomes a liquid.

• condensation

• evaporation

• deposition

Particles of a liquid are...

• Are tightly packed together and stay in a fixed position.

• Are free to move around one another but still touch.
