4. One mole of liquid water is converted into a water vapour at a temperature of 100°C and 1 atm of pressure. The enthalpy of vapourisation of water is 40.7 kJ mol-¹ at 100°C. Calculate the work done on formation of the water vapour and (ii) what fraction of the enthalpy of vapourisation is spent on expanding the vapour
