- Homework Statement
- A closed-cycle heat pump is used to move heat from a low-temp reservoir to a high-temp reservoir with fixed temperatureTH= 450 K andTC= 320 K. If the coefficient of performance of the heat pump is less thanthat of an ideal heat pump, which of the following statements is true regarding the change in the entropies? (see image attached)
- Homework Equations
S always >= 0, where S=0 only in ideal case.
for hot reservoir, delta S = negative
for cold reservoir, deta S = positive
as it is not ideal,
total change of entropy > 0
entropy loss of hot reservoir > entropy gain of cold reservoir
why would the change in entropy of the heat pump in one cycle equals to zero?
