A gas expands isothermally from state A to state B , in the process absorbing 35

Question

A gas expands isothermally from state A to stateB, in the process absorbing 35 J of heat. It is then compressed isobarically to state C, where its volume equals that of state A. During the compression, 22 J of work are done on the gas. The gas is then heated at constant volume until it returns to state A.

How much work is done by the gas during the complete cycle?

Express your answer using two significant figures.

How much heat is transferred from the gas as it goes from B to C to A?

Express your answer using two significant figures.

Explanation / Answer

a) W = 35 - 22 = 13 J

b) -22J
