State of matter means whether a material is solid, liquid or gas.

The state of matter can be changed by heating or cooling the material.

Heating can turn a solid into a liquid. This is called melting.

Heating can turn a liquid to a gas. This is called evaporating.

Cooling can turn a gas into a liquid. This is called condensing.

Cooling can turn a liquid into solid. This is called freezing.

State of matter means whether a material is solid, liquid or gas.

The state of matter can be changed by heating or cooling the material.

Heating can turn a liquid to a gas. This is called evaporating.

Cooling can turn a gas into a liquid by condensing or it can turn a gas into a solid by depositing.

Cooling can turn a liquid into solid. This is called freezing.
