An ideal gas with f = 3 degrees of freedom starts with a volume of 6 liters, a pressure of 1.1×10^5 Pa and a temperature of 20◦C. The gas is compressed adiabatically to 2 liters, then expands at constant temperature back to 6 liters. Then it is again adiabatically compressed to 2 liters, and isothermally expands to 6 liters.

Draw the 4 steps in a P −V diagram.

Calculate the final pressure and final temperature.
