Verified Solution

Answer & Solution

Correct Answer

(A) 40,60

Step-by-step Solution

Detailed explanation

For mono atomic, \(\mathrm{n}=3\) \(\mathrm{C}_{\mathrm{p}}=\frac{5}{2} \mathrm{R}, \mathrm{C}_{\mathrm{v}}=\frac{3}{2} \mathrm{R}\) Total heat supplied to system, \(\mathrm{Q}=\mathrm{nC}_{\mathrm{p}} \Delta \mathrm{T}\) \(=\frac{5 \mathrm{nR} \Delta \mathrm{T}}{2}\) Heat…
