WHAT IS MELTING?

Back

The phase change from solid to liquid due to the absorption of heat.

Front

WHAT IS FREEZING?

Back

The phase change from liquid to solid due to the release of heat.

Front

WHAT IS VAPORIZATION?

Back

The phase change from liquid to gas, which can occur through boiling or evaporation.

Front

WHAT IS CONDENSATION?

Back

The phase change from gas to liquid, typically occurring when gas cools.

Front

WHAT IS SUBLIMATION?

Back

The phase change from solid directly to gas without passing through the liquid phase.

Front

WHAT IS DEPOSITION?

Back

The phase change from gas directly to solid without passing through the liquid phase.

WHAT IS AN ENDOTHERMIC PROCESS?

Back

A process that absorbs energy (heat) from its surroundings.
