Question

# An ideal gas is taken through the cycle $$A\rightarrow B\rightarrow C\rightarrow A$$, as shown in Fig. If the net heat supplies to the gas in the cycle is $$5\ J$$, the work done by the gas in the process $$C\rightarrow A$$ is?

A
5J
B
10J
C
15J
D
20J

Solution

## The correct option is A $$-5 J$$For cyclic process,$$Q_{cyclic} = W_{AB} + W_{BC} + W_{CA}$$$$W_{BC}=0$$(volume remains constant)$$W_{AB}=P(V_{2}-V_{1})=10(2-)=10J$$ (pressure remains constant)$$5= 10 + W_{CA} \Rightarrow W_{CA} = -5\ J$$.Physics
