Suppose 2.00 mol ice at -30°C is heated at atmospheric pressure until it is converted to steam at 140°C. For ice, water, and steam, heat capacity C, is 38, 75, and 36 JK-1 mol-1 each (it can be taken to be approximately independent of temperature). AHfus (fusion) for ice is 6.007 kJ mol- and AHvap (vaporization) for water is 40.66 kJ mol-. Steam follows the ideal gas law and the volume of 1 mol ice or water is negligible relative to that of 1 mol steam. (a) Calculate total AH for this process. (b) Calculate total AE for this process.
