A 1.00-mol sample of an ideal gas (γ = 1.40) is carried through the Carnot cycle. Before the isothermal expansion takes place, the pressure of the gas is 25.0 atm and the temperature is 600 K. Before the isothermal compression, the pressure is 1.00 atm and the temperature is 400 K. Determine the pressures and volumes at all end points in the Carnot cycle (at each end point, the cycle switches between different processes).

A Carnot cycle is conducted using an ideal diatomic gas. Initially, the gas is at temperature 25C., pressure of 100KPa and volume of 0.01m3. The system is then compressed isothermally to a volume 0.002m3. From that point, the gas undergoes an adiabatic compression ( with gamma= 1.4), until the volume further reduces to 0.001m3. After that, the system goes an isothermal expansion process to a point where the pressure of the system is 263.8KPa. Then the system continues the cycle...
