Heat is present in the molecule as the energy due to motions in the molecule. This heat is expressed in the units of calories $\left(\text{cal}\right)$ or joules $\left(\text{J}\right)$. Vaporization is a process of conversion of a liquid into gas at its boiling point. Heat is supplied to the system during the process of vaporization.
