Vertices of a triangular cycle on a

P

–

V

diagram are:

A\,(1.0 \times 10^{5}\,\text{Pa},\;0.02\,\text{m}^3)

B\,(3.0 \times 10^{5}\,\text{Pa},\;0.02\,\text{m}^3)

C\,(1.0 \times 10^{5}\,\text{Pa},\;0.06\,\text{m}^3)

. The path is traversed anticlockwise

A \rightarrow B \rightarrow C \rightarrow A

. Determine the net heat exchanged with the gas in one cycle. a)
