Consider a heat pump that is used to cool down a home during the summer. Its coefficient of performance in cooling mode is 5.81. On a particularly hot day, the temperature outside the home is 90◦F, and the temperature inside the home is maintained at 70◦F. If the heat pump consumes 500 W of electrical power, at what rate does it remove heat (W) from the home?
