A 2.50 mole sample of an ideal gas, for which CV ,m = 3/2 R, is subjected

Question:

A 2.50 mole sample of an ideal gas, for which _{CV ,m} = 3/2 R, is subjected to two successive changes in state:

a) From 25.0°C and 125. × 10³ Pa, the gas is expanded isothermally against a constant pressure of 15.2 × 10³ Pa to twice the initial volume.

b) At the end of the previous process, the gas is cooled at constant volume from 25.0°C to –29.0°C. Calculate q, w, ΔU, and ΔH for each of the stages. Also calculate q, w, ΔU, and ΔH for the complete process.
