Question

A diatomic ideal gas acts as a heat engine following a process described by the diagram below: Step 1. Isothermal expansion at Thot from volume Va to a final volume Vb. The final volume is a factor k times larger than the initial volume (ie. Vb=kVa). Step 2. Isobaric contraction from volume Vb back to original volume Va, and cooling from Thot to Tc Step 3. Isochoric heating returning the system to its original state. P a 1 3 c 2 b V If there are n=76.2mols of the gas, the expansion factor k=3.8, and initial temperature Thot =229.1K, what is the change in entropy of the gas during the isothermal expansion? Answer in Joules per Kelvin.
