Water is being cooledd in a closed container while being stirred by a paddle wheel. During this process, 25 kJ of heat is taken away from the water, and 15 kJ of heat is added to the water. The paddle-wheel work amounts to 5 N.m. Determine the final energy of the system if its initial energy is 10 kJ. (Sketch the system boundaries)

A heat engine operates between thermal energy stores at 800 ° C and 20 ° C. Half of the power generated by the heat engine drives the Carnot heat pump, which is used to heat a house. While the interior temperature of the house is 22 ° C, the outside temperature is 2 ° C, the heat loss of the house is 62000 kJ / h. In these conditions, calculate the minimum heat that should be given to the heat machine per unit time as kW.

A heat pump used for heating shown 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 device’s 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 20.0°C and the outside temperature is -5.00°C.
