To determine
Explanation of the statement “the first law of thermodynamics says we can’t get more out of a process then we put in, but the second law says that we can’t break even”.

Explanation

The first law of thermodynamics states that “the change in internal energy of a system is equal to the heat added to the system minus the work done by the system”. The second law of thermodynamics says that, it is not possible for heat to flow from a colder body to a warmer body without any work which is done to do this flow of heat.

From the first law of thermodynamics, “the change in internal energy of a system is equal to the heat added to t...
