Coefficient of Performance of a Domestic Refrigerator
Coefficient of Performance (COP) is a measure of the efficiency of a refrigerator. It is defined as the ratio of the heat removed from the refrigerator to the work done by the compressor.
COP = Heat Removed / Work Done
A domestic refrigerator is a type of vapor compression refrigeration system that uses a refrigerant to transfer heat from the inside of the box to the outside environment. The compressor is used to increase the pressure of the refrigerant, which causes it to release heat as it condenses. The refrigerant then evaporates inside the box, absorbing heat from the inside.
Answer: B) More than 1
Explanation:
The COP of a domestic refrigerator is more than 1 because the heat removed from the inside of the box is greater than the work done by the compressor. This means that for every unit of work done by the compressor, more than one unit of heat is removed from the inside of the box.
In other words, a COP of 1 means that the heat removed is equal to the work done. A COP greater than 1 means that more heat is removed than the work done, which is desirable for a refrigerator.
Therefore, the correct answer is option B) More than 1.
