Correct Answer Both b and c are correct

CONCEPT:

S.No.

Refrigerator

 Heat pump
1.

A refrigerator is a device that maintains a system or a body at a temperature lower than the surrounding temperature.

A heat pump is a device that maintains a system or a body at a temperature higher than the surrounding temperature.
2.

In the refrigerator, the heat is removed from the low-temperature body and is rejected to the high-temperature body.

In the heat pump, the heat is removed from the low-temperature body and is added to the high-temperature body.
3.

Generally, the surrounding atmosphere acts as the high-temperature body for a refrigerator.

Generally, the surrounding atmosphere acts as the low-temperature body for a heat pump.

EXPLANATION:

  • A refrigerator is a device that maintains a system or a body at a temperature lower than the surrounding temperature.
  • A heat pump is a device that maintains a system or a body at a temperature higher than the surrounding temperature.
  • Hence, option 3 is correct.

Consider the following statement: a) In a refrigerator the heat is taken out from the system. b) In a refrigerator the heat is given to the system. c) In a heat pump the heat is taken out from the system. d) In a heat pump the heat is given to the system. Which of the above statements are correct?
Two refrigerators M and N operate in series. The refrigerator M absorbs energy at the rate of 1 kW from a body at temperature 400 K and rejects energy as heat to a body at a temperature T. The refrigerator N absorbs the same quantity of energy which is rejected by the refrigerator N from the body at temperature T, and rejects energy as heat to a body at temperature 800 K. If both the refrigerators have the same C.O.P., what is the value temperature T?
