A certain gas process ends in its original thermodynamics state. Of the following, which is possible as the net result of the process?

A certain gas process ends in its original thermodynamics state. Of the following, which is possible as the net result of the process?

Explanation

Since ΔU = 0 for a cyclic process, Q = W.

The gas absorbs 50 J of energy as heat and does 50 J of work, where Q = W = 50 J.

The best answer is The gas absorbs 50 J of energy as heat and does 50 J of work.
