A refrigerator that consumes 3 kW of electricity when running and has a coefficient of performance of 1.5 is placed in a well-sealed room, and is plugged in with its door open. The rate of cooling or heating this refrigerator will provide to the air in the room when running isQuestion 8Select one:a.3 kJ/s, coolingb.4.5 kJ/s, coolingc.2 kJ/s, heatingd.4.5 kJ/s, heatinge.3 kJ/s, heating

Multiple Choice QuestionHow does a heat pump work to keep your refrigerator cool?Multiple choice question.A refrigerant liquid is compressed and gives of heat to its surrounding as it does so.A refrigerant liquid is allowed to expand and absorbs heats from its surroundings as it does so.

Select the most accurate response. Refrigerators and heat pumps are both systems which transfer energy from low-temperature reservoirs to high-temperature reservoirs, against the natural direction of heat transfer. The purpose of a refrigerator is to keep an enclosed space cool. The purpose of a heat pump is:Question 6Select one:a.to remove heat from a colder spaceb.to remove heat from a warmer spacec.to supply heat to a colder spaced.to supply heat to a warmer space

The air in a kitchen has pressure 1.0 × 105 Pa and temperature 22°C. A refrigerator of internalvolume 0.36 m3 is installed in the kitchen.(a) With the door open the air in the refrigerator is initially at the same temperature andpressure as the air in the kitchen. Calculate the number of molecules of air in therefrigerator.
