For nitrogen gas the values of Cv and Cp at 25oC are 20.8 J K-1 mol-1 and 29.1 J K-1 mol-1, respectively. When a sample of nitrogen is heated at constant pres-sure, what fraction of the energy is used to increase the internal energy of the gas? How is the remainder of the energy used? How much energy is required to raise the temperature of 100.0 g N2 from 25.0oC to 85.0oC in a vessel having a constant volume?
