6.00 mol of an ideal gas with Cv.m = 1.5R undergo a two-step process. Calculate q, w, ΔU, and ΔH for each step and for the total process.
Step A: Isothermal compression at 305K under a constant pressure of 10.0 bar from an initial pressure of 2.00 bar.
Step B: After step A, the system is cooled at constant volume to 285K.
Thank you

Suppose that we allow 3.50 mol of an ideal gas with Cv=5R/2 to expand isothermally and reversibly from 100 atm, 10 L to 10.0 atm and then the gas is allowed to expand adiabatically and reversibly to a final pressure of 1.00 atm. Calculate q, w, ΔU and ΔH for each step and the total values for the two steps. Suppose now that the processes are carried out irreversibly with pressure dropping discontinuously from 100 atm to 10.0 atm in...

7.5) A 1.15 -mol quantity of monatomic ideal gas undergoes the
following cyclic process. The gas starts at point a at STP. It
expands isothermally to point b, where the volume is 2.2 times its
original volume. Next, heat is removed while keeping the volume
constant and reducing the pressure. Finally, the gas undergoes
adiabatic compression, returning to point a.
