QUESTION:
Problem 27E
Three moles of an ideal gas undergo a reversible isothermal compression at 20.0o C. During this compression, 1850 J of work is done on the gas. What is the change of entropy of the gas?
ANSWER:Solution to 27E
Step 1
For an isothermal expansion, △T=0, and △U=0. Therefore,
△U=△Q-△W
0=△Q-△W
△Q=△W……………………………………………………………………………(1)
Work done on the gas= 1850 J
