(D) refrigerator works on the principle of a heat pump,which extracts heat from the cooling chamber and rejects it into the surrounding environment. According to the first law of thermodynamics,the energy rejected into the room is equal to the heat extracted from the cooling chamber plus the work done by the compressor. Since the compressor consumes electrical energy to perform work,the total heat released into the room is greater than the heat removed from the cooling chamber. Therefore,if the door of a refrigerator is left open in a well-insulated room,the net effect will be an increase in the temperature of the room.

The door of a working refrigerator is left open in a well-insulated room. The temperature of the air in the room will

Can the coefficient of performance of a refrigerator be increased by increasing the mass of the working substance?

The temperature inside a refrigerator is $t_2 \, ^\circ C$ and the room temperature is $t_1 \, ^\circ C$. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be:

Define and write the formula for the coefficient of performance of a refrigerator.

$A$ refrigerator of coefficient of performance $5$ that extracts heat from the cooling compartment at the rate of $250 \ J$ per cycle is placed in a room. The heat released per cycle to the room by the refrigerator is (in $J$)
