The heat of evaporation of water at atmospheric pressure is Lv 2260 kJ/kg. a. How much of this heat represents work done to expand the water into steam against the pressure of the atmosphere? b. What becomes of the rest of the heat? At T= 100°C and p=1.0 atm, the density of water is 1.00 × 10³ kg/m³ and the density of steam is 0.600kg/m³?
