Question
In which system is heat usually transferred from the cooler part to the warmer part?Select one:a.none of the above, because it is impossible to transfer heat in this mannerb.a refrigerator that is runningc.a stove as it heats up waterd.an electric fan that is running
Solution
The correct answer is b. a refrigerator that is running.
This is because a refrigerator works by transferring heat from the inside (cooler part) to the outside environment (warmer part), thus cooling the items inside. This process is facilitated by the refrigerator's refrigeration cycle, which involves the evaporation and condensation of a refrigerant fluid.
This is an exception to the second law of thermodynamics, which states that heat naturally flows from a body at a higher temperature to a body at a lower temperature. In the case of the refrigerator, this natural flow is reversed with the help of work done by the refrigerator's compressor.
