I think C is the answer

c) both of the mentioned above

hey mate I hope it helped u..plz mark it as brainliest

Explanation:

coz a heat pump provides heat at high temperature and a refrigerator removes the heat for cooling..

Answer 2

The correct response to the given question is option c: Both of the mentioned options (a and b).

Refrigerator:

• A refrigerator is a device that removes heat from the food kept inside and archives the cooling effect.
• This uses refrigerant which can easily expand to gases when inside the refrigerator and can be compressed back to liquid when outside the refrigerator.
• In the gaseous form this coolant expands and takes up heat and as a heat conveyor outside the refrigerator, it is compressed to liquid releasing the heat.
• In this way, the refrigerator removes heat to achieve cooling inside the refrigerator.

Heat pump:

• The heat pump system extracts heat from the cooler environment outside the enclosed system and through the compressor, the temperature of this is increased.
• It then provides warm air inside the enclosed environment.
• Hence, options a and b are true.
