Calculate the energy required to change the temperature of 1.00 kg of ethane (C2H6) from 25.0oC to 73.4oC in a rigid vessel. (Cv for C2H6 is 44.60 J K-1 mol-1.) Calculate the energy required for this same temperature change at constant pressure. Calculate the change in internal energy of the gas in each of these processes.
