B) 2nd Law of Thermodynamics: For a closed system the total entropy increases for an irreversible process or stays constant for a reversible process. This is known as the 2nd Law of Thermodynamics: AS total ≥ 0. 1) Imagine two reservoirs (large systems so that their temperature stays constant) at different temperatures exchanging heat. Draw two separate T-S diagrams, one for the high temperature and one for the low temperature reservoir. Decide whether entropy should be increasing or decreasing for each reservoir, and depict this on each diagram. 2) Which quantity should be the same for each reservoir? Why? 3) Based on your answer in 2) make appropriate adjustments to your T-S diagrams. Which reservoir has a larger change in entropy (in terms of magnitude of AS)? 4) If the two reservoirs constituted a closed system, is the total entropy increasing or decreasing? Does this agree with the 2nd Law of Thermodynamics?

Question
B) 2nd Law of Thermodynamics:
For a closed system the total entropy increases for an irreversible process or stays constant for a reversible
process. This is known as the 2nd Law of Thermodynamics:
4Stotal ≥ 0.
1) Imagine two reservoirs (large systems so that their temperature stays constant) at different
temperatures exchanging heat. Draw two separate T-S diagrams, one for the high temperature and
one for the low temperature reservoir. Decide whether entropy should be increasing or decreasing
for each reservoir, and depict this on each diagram.
2)
Which quantity should be the same for each reservoir? Why?
3) Based on your answer in 2) make appropriate adjustments to your T-S diagrams. Which reservoir
has a larger change in entropy (in terms of magnitude of AS)?
4)
If the two reservoirs constituted a closed system, is the total entropy increasing or decreasing?
Does this agree with the 2nd Law of Thermodynamics?
