Problem: According to the second law of thermodynamics, it is impossible for ____________.a) heat energy to flow from a colder body to a hotter bodyb) an ideal heat engine to have the efficiency of 99%c) an ideal heat engine to have non-zero power.d) a physical process to yield more energy than what is put in

FREE Expert Solution

The law of conservation of energy prohibits the yield of more energy than the input.

The second law provides that it is not possible to transfer heat from a colder body to a hotter body without help from an external agency.
