2.2Consider the change in phase from liquid water to watervapour at 100°C. The vapour pressure is 1 atm. Thespecific volumes of vapour and liquid are 1.8 m³kg¹ and0.001 m³kg¹ respectively. (Take the latent heat ofvapourisation of water at atmospheric pressure is 22.6 x10³ J Kg¹¹.)(a) Find the percentage of the heat of vapourisation thatgoes into the increase of internal energy.(b) What happens to the remaining heat?(c) Determine by how much the specific entropy of steamexceeds that of liquid water.
