Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 350 K is heated at constant volume to 700 K, allowed to expand isothermally to its initial pressure, and finally compressed at constant pressure to its original volume, pressure, and temperature.
(a) What is the net energy entering the system (the gas) as heat during the cycle? (J)
(b) What is the net work done by the gas during the cycle? (J)
(c) What is the efficiency of the cycle? (%)
