Chapter 9, Problem 91AE

Consider the following cyclic process carried out in two steps on a gas:

$\text{Step 1}$ : $\text{45 J}$ of heat is added to the gas, and $\text{10}\text{. J}$ of expansion work is performed.

$\text{Step 2}$ : $\text{60}\text{. J}$ of heat is removed from the gas as the gas is compressed back to the initial state. Calculate the work for the gas compression in $\text{Step 2}$ .
