Changing states Matter can change from one state to another when heat energy is released or absorbed. This is called a change of state.

Melting The change from the solid state to the liquid state is melting. The temperature at which a substance changes from a solid to a liquid is called the melting point. Melting is when matter absorbs heat energy, and its temperature rises.

Freezing The change from the liquid state to the solid state is called freezing. The temperature at which a substance changes from the liquid state to the solid state is called the freezing point. Energy is released during freezing.

Evaporation The change from the liquid state to a gas state is known as evaporation. The temperature at which a liquid boils is called the boiling point.

Condensation As a gas cools, its particles slow down.
The process of a gas changing to a liquid is called condensation. This process is the opposite of evaporation.
