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.

Start with an ideal gas of volume 4m^3, at a pressure of 1200Pa, and temperature 289K. Construct a cycle using 3 or more processes (of your choice). For each process in your cycle calculate the Q, ?U, and W. Calculate the net change in each of these quantities for the entire cycle, and determine whether the work as a result of the cycle is done ON or BY the system.

The volume of some air, assumed to be an ideal gas, in the cylinder of a car engine is 540cm^3 at a pressure of 1.1 x 10^5 Pa and a Temperature of 27 Degree celsius. The air is suddenly compressed, so that no thermal energy enters or leaves the gas, to a volume of 30cm^3. The pressure rises to 6.5 x 10^6 Pa. Determine the Temperature of the gas after compression.
