A quantity of heat ' Q ' is supplied to monoatomic ideal gas which expands at constant pressure. The fraction of heat converted into work is \(\left[\gamma=\frac{C_p}{C_v}=\frac{5}{3}\right]\)
- A \(3: 5\)
- B \(5: 3\)
- C \(2: 5\)
- D \(3: 2\)
Answer & Solution
Correct Answer
(C) \(2: 5\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \frac{\Delta Q}{\Delta U}=\frac{C_p}{C_v}=\gamma \\ \therefore \quad & \frac{\Delta Q}{\Delta U}=\frac{5}{3} \\ & \frac{\Delta Q-\Delta U}{\Delta Q}=\frac{5-3}{5} \ldots(\text { Applying dividend) } \\ \therefore \quad & \frac{W}{\Delta Q}=\frac{2}{5}\end{aligned}\)
