Repeat Problem 3.4-3 for CO₂, rather than for a monatomic ideal gas. Assume CO₂ can be represented by an ideal van der Waals fluid with constants as given in

Problem 3.4-3

Two moles of a monatom1c ideal gas are at a temperature of 0°C and a volume of 45 liters. The gas is expanded adiabatically ( dQ = 0) and quasi-statically until its temperature falls to - 50°C. What are its imtial and final pressures and its final volume?
