Chapter 9, Problem 42E

Consider a sample containing $\text{2}\text{.00 moles}$ of a monatomic ideal gas that undergoes the following changes:

For each step, assume that the external pressure is constant and equals the final pressure of the gas for that step. Calculate $\text{q}$ , $\text{w}$ , $\text{ΔE}$ , and $\text{ΔH}$ for each step and for the overall change from state A to state D.
