Given the coefficient of performance of a heat pump is 1.25 and the heat released into the hot reservoir is 92 W, what is the heat required from the cold reservoir and what is the work required for this output?
Q_cold = 162.7 W and Work = 79.7 W
Q_cold = 115 W and Work = 23 W
Q_cold = 18.4 W and Work = 73.6 W
Q_cold = 73.6 W and Work = 18.4 W
