Consider the heat engine shown below, operated in contact with a cold thermal reservoir at temperature Tc = 25 °C and a hot thermal reservoir at temperature TH = 290 °C.
Suppose in one cycle, the engine draws 1200 J of heat from the hot thermal reservoir. What is the maximum work the engine can do in this cycle?
(a) 2.13e+00 J
(b) 5.65e+02 J
(c) 1.10e+03 J
(d) 1.20e+03 J
(e) 5.48e+02 J
Which of the following would ensure that the engine can achieve the maximum theoretical work?
(a) None of these
(b) The cycle is reversible.
(c) The change in entropy of the engine over the cycle is zero.
(d) The engine is a Stirling engine.
(e) The cycle is quasistatic.
