of water at is placed in the freezer compartment of a refrigerator with a coefficient of performance of . How much heat energy is exhausted into the room as the water is changed to ice at ?
As a result, the heat emitted into the room is.
The heat energy of a specific mass with a specific heat capacity that is subjected to a temperature difference is given as:
Where m is the body's mass and C is its specific heat capacity and is the temperature difference.
The mass of the water sample is :
The heat energy extracted from water is known as:
The performance metric is:
As a result, the work input is
The heat that is emitted into the room is:
As a result, the amount of heat emitted into the room is reduced .
