Suppose 1.00 mol ice at –30°C is heated at atmospheric pressure until it is converted to steam at 140°C. Calculate q, w, AH, and AU for this process. For ice, water, and steam, cp is 38, 75, and 36 J K-1 mol¬1, respectively, and can be taken to be approximately independent of tempera- ture. AHfus for ice is 6.007 kJ mol=1, and AHvap for water is 40.66 kJ mol-1. Use the ideal gas law for steam, and assume that the volume of 1 mol ice or water is negligible relative to that of 1 mol steam.
