Question

He gas is confined to a piston and cylinder. The initial temperature of the gas is 298 K, the volume of gas in the

cylinder is 1.20 L, the pressure is 2.15 bar and the amount of He is 0.104 mol. The ideal gas EOS is very accurate for He under these conditions. The molar heat capacity of He at constant volume is 12.472 J K-1 mol-1. The gas undergoes reversible adiabatic expansion until the pressure in the cylinder is 1.12 bar.

a) What is the final volume and temperature of the gas?

b) What is w, q, and ΔU (in J) for the process?
