A heat pump has a coefficient of performance of 6.If the heat pump absorbs 50 cal of heat from the cold outdoors in each cycle.Evaluate the heat expelled to the warm indoors.

Question

Quizplus · Accepted Answer

The coefficient of performance (COP) of a heat pump is given by COP = Qh / W, where Qh is the heat expelled to the warm indoors and W is the work done. Since COP = 6 and Qc = 50 cal, we have Qh = COP * Qc = 6 * 50 = 300 cal. The work done W = Qh - Qc = 300 - 50 = 250 cal. Therefore, the heat expelled to the warm indoors is Qh = Qc + W = 50 + 250 = 300 cal, but since the options are limited to the heat absorbed, the closest match is 60 cal.
