An ideal gas is taken through the cycle \(A \rightarrow\) \(B \rightarrow C \rightarrow A\) as shown in the figure. If the net heat supplied to the gas in the cycle is \(5 \mathrm{~J}\). The magnitude of work done during the process \(C \rightarrow A\) is
- A \(5 \mathrm{~J}\)
- B \(10 \mathrm{~J}\)
- C \(15 \mathrm{~J}\)
- D \(20 \mathrm{~J}\)
Answer & Solution
Correct Answer
(A) \(5 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
An ideal gas is taken through the cycle \(A \rightarrow B \rightarrow C \rightarrow A\) as shown in the figure, From the graph, \(\begin{aligned} W_{A B} & =P \times d V \\ & =10 \times(2-1)=10 \mathrm{~J} \end{aligned}\) Similarly, \(W_{B C}=P \times(0)=0 \mathrm{~J}\)…
