Problem
A 1.00 mol sample of an ideal gas at 300 K undergoes two successive isothermal steps:
1. Expansion from 5.00 L to 15.00 L
2. Compression from 15.00 L to 8.00 L
What is the net entropy change, ΔSnet, for the gas after both steps are complete?
(a) +14.4J K−1
(b) −3.9J K−1
(c) +3.9J K−1
(d) +1.7J K−1
