Question

Of the following, which is not a statement of the second law of thermodynamics?

A)The entropy of the Universe increases in all natural processes.
B)No real engine operating between two energy reservoirs can be more efficient than a Carnot engine operating between the same two reservoirs.
C)No heat engine operating in a cycle can absorb energy from a reservoir and use it entirely to do work.
D)In all real processes, the resulting energy available for doing work decreases.
E)When a system undergoes a change in state, the change in the internal energy of the system is the sum of the energy transferred to the system by heat and the work done on the system.

Explanation / Answer

E)When a system undergoes a change in state, the change in the internal energy of the system is the sum of the energy transferred to the system by heat and the work done on the system.

This is the statement for the first law. Rest are all 2nd law forms.
