Suppose we slowly push the piston back to its original position in Figure 21.6, all the while

Question:

Suppose we slowly push the piston back to its original position in Figure 21.6, all the while maintaining a constant temperature in the gas.

(a) Over the time interval that includes the expansion and the compression of the gas, has any energy been converted?

(b) Does the entropy of the gas increase, stay the same, or decrease over that time interval?

(c) If we keep repeating the expansion and compression, is this device a steady device?
