A heat pump uses an ideal Carnot cycle to heat a house. The outside air has a temperature of 294 K and the house is kept at a temperature of 304 K.

Coefficient of performance of this heat pump: TH/(TO-TH) = 304/(294-304) = 30.4

1) If the heat pump does 1500 J of work on the working substance, how much energy is transferred into the house?

2) In the scenario described in the previous question, how much energy is transferred out of the outside air?
