Step 1:Definition : The process of changing of a gas into a liquid by cooling is called as condensation.
Step 2: Explanation: 1)When a gas is cooled enough by lowering its temperature, its particles lose kinetic energy and
move slowly until they come closer and get attracted to each other to form a liquid. 2)The process of condensation is the reverse of boiling or vaporisation.
Srep 3: Example: 1)Morning dew on grass. 2) Fog in air. 3) Visible breath in cold conditions.
