Can someone please explain this physical chemistry question to me:
A 1.60 mol sample of an ideal gas for which (P =\) 2.06 bar and (T =\) 331 K is expanded adiabatically against an external pressure of 0.230 bar until the final pressure is 0.250 bar
Part A Calculate the final temperature for Cv,m = 3R/2
Part C Calculate w for Cv,m = 3R/2
Part D Calculate ΔH for Cv,m = 3R/2
Part E Calculate ΔU for Cv,m = 3R/2
Part F Calculate the final temperature for Cv,m = 5R/2
