1 mole of ice at 0C and 4.6 mm Hg pressure is converted to water vapour at a constant temperature and pressure.
Find Delta H and Delta E if the latent heat of fusion of ice is 80 calg and latent heat of vaporisation of liquid water at 0C is 596 calg and the volume of ice in comparison to that of water vapour in neglected.
