Particles of water vapour at 100oC (373K) have more energy than liquid water at
               same temperature. this due to the absorption of extra energy in the form of latent
               heat of vaporisation.

               Latent heat of vaporisation: The heat energy required to convert 1 kilogram of
               liquid into gas, at atmospheric pressure, at its boiling point, is known as the latent
               heat of vaporisation
               Note: Water vapour at 373 K have more energy than water at the same temperature
               because
               particles in steam have absorbed extra energy in the form of latent heat of
               vaporisation.
