A 29-L sample of an ideal gas with γ=1.67 is at 250 K and 50 kPa . The gas is compressed adiabatically until its pressure triples, then cooled at constant volume back to 250 K, and finally allowed to expand isothermally to its original state. How much work is done on the gas? What is the minimum volume reached?
