A heat pump requires $500 \mathrm{W}$ of electrical power to deliver heat to your house at a rate of $2400 \mathrm{J}$ per second. How many joules of energy are extracted from the cold air outside each second?
An ideally efficient heat pump delivers 700 J of heat to room air at 295 K. If it extracted heat from 265 K outdoor air, how much of that delivered heat was originally work consumed. in the transfer?

A heat pump extracts 7.0 × 106 J of heat per hour from a well at 280 K and delivers its output heat into a house at 320 K. If the heat pump uses an ideal Carnot cycle in its operation, what minimum work must be supplied to the heat pump per hour?
