What is evaporation and condensation?
Evaporation and condensation
Liquids and gases can be changed from one state to another by heating or cooling.
Heat can turn a liquid into a gas and cooling can cause a gas to turn to a liquid.
If water (liquid) is heated, it changes to water vapour (gas). This change is called evaporation.
If water vapour (gas) is cooled down, it changes into water (liquid). This change is called condensation.
