Deduce a value for the latent heat of evaporation Lv of water. State clearly any simplifying assumptions that you make. Estimate the pressure at which ice and water are in equilibrium at −2◦C given that ice cubes float with 4/5 of their volume submerged in water at the triple point (0.01◦C, 612Pa). [Latent heat of sublimation of ice at the triple point, Ls = 2776 °´ 103 Jkg−1.]
