Serway & Jewett β Heat Engines, Entropy, and the Second Law of Thermodynamics: Problem 17
A heat pump used for heating shown in Figure P21.17 is essentially an air conditioner installed backward. It extracts energy from colder air outside and deposits it in a warmer room. Suppose the ratio of the actual energy entering the room to the work done by the deviceβs motor is 10.0% of the theoretical maximum ratio. Determine the energy entering the room per joule of work done by the motor given that the inside temperature is 20.0Β°C and the outside temperature is -5.00Β°C.

Given: 20.0Β°C, 5.00Β°C
