A sample of 1.00 mol of perfect gas molecules, originally at 1.00 atm, with a molar heat capacity at constant pressure of 7/2 R is put through the following cycle: a. constant volume heating to twice its initial temperature, where ?T = 298 K, b. reversible, adiabatic expansion back to its initial temperature, c. reversible, isothermal compression back to 1.00 atm
