Select the specific statement of the 2nd Law that applies: A process with a negative entropy generation is not physically possible. Clausius Statement Ideal Gas Law Statement Boltzmann Statement Entropy Statement Kelvin-Planck Statement

Answer 1

Ans. Clausius statement

Clausius inequality $\oint_{}^{}$ (dQ/T) $\leq$ 0 .

The equal sign in clausius inequality applies to ideal or carnot cycle. Since integral represents the net change in entropy in one complete cycle and makes it clear entropy does not decrease even in an ideal engine cycle.
