Phase Changes

Front

What is a phase change?

Back

A phase change is a transition of matter from one state to another, such as solid, liquid, gas, or plasma.

Front

What are the four main states of matter?

Back

Solid, Liquid, Gas, Plasma.

Front

What happens to molecules during melting?

Back

Molecules absorb energy, move faster, and break free from their fixed positions.

Front

What is freezing?

Back

Freezing is the phase change from liquid to solid, where molecules lose energy and move closer together.

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid, where gas molecules lose energy and come together.

Front

What is evaporation?

Back

Evaporation is the phase change from liquid to gas, where liquid molecules gain energy and move apart.

Front

What is boiling?

Back

Boiling is a rapid phase change from liquid to gas that occurs throughout the liquid at a specific temperature.

Front

What is sublimation?

Back

Sublimation is the phase change from solid directly to gas without passing through the liquid state.

Front

What is deposition?

Back

Deposition is the phase change from gas directly to solid without becoming a liquid.

Front

How does temperature affect phase changes?

Back

Temperature changes can add or remove energy, causing matter to change from one phase to another.
