Calculate the entropy change for the gas.

Extracted text: Suppose the n-mole ideal gas in the figure expands to four times its initial volume. For this process, the initial and final temperatures are the same. Calculate the entropy change for the gas. (We can do the calculation by using the isothermal process between the initial and final states of the gas.)
