2.15 mol of an ideal gas with CV,m=3R/2undergoes the transformations described in the following list froman initial state described by T=350.K andP=5.00bar.
1) The gas undergoes a reversible adiabatic expansion until thefinal pressure is one-fourth its initial value.
2) The gas undergoes an adiabatic expansion against a constantexternal pressure of 1.25 bar until the final pressure isone-fourth its initial value.
3)The gas undergoes an expansion against a constant externalpressure of zero bar until the final pressure is equal toone-fourth of its initial value.
