Suppose that 238 moles of a monatomic ideal gas is initially contained in a piston with a volume of 1.2 m at a temperature of 507 K. The piston is connected to a hot reservoir with a temperature of 1277 K and a cold reservoir with a temperature of 507 K. The gas undergoes a quasi-static Stirting cycle with the following steps: 1. The temperature of the gas is increased to 1277 K while maintaining a constant volume. 2. The volume of the gas is increased to 3.91 m while maintaining a constant temperature. 3. The temperature of the gas is decreased to 507 K while maintaining a constant volume. 4. The volume of the gas is decreased to 1.2 m while maintaining a constant temperature. It may help you to recall that Cy 12.47 JIK/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 - 10) times the number of moles of the gas. 1) What is the pressure of the gas under its initial conditions?

temperature of 507 K. The piston is connected to a hot reservoir with a temperature of 1277 K and a cold reservoir with
a temperature of 507 K. The gas undergoes a quasi-static Stirling cycle with the following steps:
1. The temperature of the gas is increased to 1277 K while maintaining a constant volume.
2. The volume of the gas is increased to 3.91 m while maintaining a constant temperature.
3. The temperature of the gas is decreased to 507 K while maintaining a constant volume.
4. The volume of the gas is decreased to 1.2 m while maintaining a constant temperature.
It may help you to recall that Cy 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is
equal to Avagadros number (6.022 x 10") times the number of moles of the gas.
