Solution:

The change of state from liquid to vapour (for gas) is called vapourisation. It is observed that when liquid is heated, the temperature remains constant untill the entire amount of the liquid is converted into vapour. The temperature at which the liquid and the vapour states of the substance coexists is called its boiling point.
