We have a container of compressed air. Assume that air is diatomic ideal gas. The volume of the container is 1.35 liters. The pressure of the gas is 2.67 atm, and its temperature is 19'C. We allow the gas to expand adiabatically to a final pressure of 1.00 atm.
(a) Find the final volume of the gas.
(b) Find the final temperature of the gas.
(c) Find the change of internal energy of the gas.
(d) Find the work done by the gas.
