Suppose the temperature of the hot reservoir is increased by 16 K, from 576 K to 592
Question:
Suppose the temperature of the hot reservoir is increased by 16 K, from 576 K to 592 K, and that the temperature of the cold reservoir is also increased by 16 K, from 305 K to 321 K.
(a) Is the new efficiency greater than, less than, or equal to 0.470? Explain.
(b) What is the new efficiency?
(c) What is the change in entropy of the hot reservoir when 1050 J of heat is drawn from it?
(d) What is the change in entropy of the cold reservoir?
