Question:

Consider 132 moles of a monatomic gas undergoing the isothermal expansion shown in Figure 18-28.

(a) What is the temperature T of this expansion?

(b) Does the entropy of the gas increase, decrease, or stay the same during the process? Explain. 

(c) Calculate the change in entropy for the gas, ΔS, if it is nonzero.

(d) Calculate the work done by the gas during this process, and compare to TΔS.
