A piston contains 320 moles of an ideal monatomic gas that initally has a pressure of 2.38 x 10° Pa and a volume of 1.8
m. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle
accepting energy from the hot reservoir and exhausting energy into the cold reservoir.
1. The pressure of the gas is increased to 5.38 x 10° Pa while maintaining a constant volume.
2. The volume of the gas is increased to 8.8 m³ while maintaining a constant pressure.
3. The pressure of the gas is decreased to 2.38 x 10° Pa while maintaining a constant volume.
4. The volume of the gas is decreased to 1.8 m³ while maintaining a constant pressure.
It may help you to recall that Cv = 12.47 J/K/mole and Cp = 20.79 J/K/mole for a monatomic ideal gas, and that the
number of gas molecules is equal to Avagadros number (6.022 x 1023) times the number of moles of the gas.
