Chapter 3, Problem 3.54E

One mole of ideal gas expands isothermally and reversibly by $1.00\text{L}$. In one case, the expansion starts at $1.00\text{L}$, and in a second case, the expansion starts at $10.00\text{L}$. Calculate the entropy changes for both expansions and justify the relative values in terms of the change in $\Omega$ for each expansion.
