A thermoelectric cooler is a type of heat pump that uses electric power to move heat against its natural direction of flow. In such a heat pump electrical power must be converted to thermal energy because,
A. the entropy of the system must be conserved.
B. Newton's laws of motion prevent heat from moving from a cool region to a warm region.
C. the flow of heat from a cool region to a warm region alone would decrease the entropy (disorder) of the system.
D. the flow of heat from a cool region to a warm region alone would violate the conservation of energy.
