Consider the change in phase from liquid water to water
vapour at 100°C. The vapour pressure is 1 atm. The
specific volumes of vapour and liquid are 1.8 m³kg ¹ and
0.001 m³kg¹ respectively. (Take the latent heat of
vapourisation of water at atmospheric pressure is 22.6 x
105 J Kg ¹.)
(a) Find the percentage of the heat of vapourisation that
goes into the increase of internal energy.
(b) What happens to the remaining heat?
(c) Determine by how much the specific entropy of steam
exceeds that of liquid water.
