Question
Is the transfer of heat from cold space inside the refrigerator to warm surrounding against the second law of thermodynamics? Explain.
Solution
According to the second law of thermodynamics, the heat cannot flow spontaneously from a body at low temperature to a body at high temperature. An external force is required for the transfer of heat energy.
In case of the refrigerator, the external agency is the compressor that does the work to transfer the heat.
