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 the isothermal expansion and from 10.0 atm to 1.0 atm in the adiabatic expansion. Calculate q, w, ΔU and ΔH for each step and the total values for the two steps.

    One mole of an Ideal Gas, for which Cv,m = 3/2R, initially at 20.0 C and 1.00 x106 Pa undergoes a two-stage transformation: Stage 1: The gas is expanded isothermally and reversibly until the volume doubles. Stage 2: Beginning at the end of the first stage, the temperature is raised to 80.0 C at constant volume. For each stage, calculate the final pressure, heat(q), work(w), change in internal energy (ΔU), and enthalpy (ΔH). Calculate the total q, w, ΔU, and...
