Consider a cylinder-piston system that contains one mole of an ideal diatomic gas at 4 atmospheres and 81.85 ° C. First, the gas expands isobarically to twice its original volume. It is then isothermally compressed to its original volume and finally, isocarically cooled to its original pressure. Determine the heat released by the gas throughout the cycle.
