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
