A) \[\frac{2}{3}Q\]
B) \[\frac{3}{5}Q\]
C) \[\frac{2}{5}Q\]
D) \[\frac{1}{5}Q\]
Correct Answer: C
Solution :
Since, we know that for monoatomic gas at constant pressure. \[\frac{\Delta U}{Q}=\frac{3}{5}\] \[\Rightarrow \] \[\Delta U=\frac{3Q}{5}\] ??.(i) Now, from first law of thermodynamics, we have \[W=\Delta Q-\Delta U\] \[=Q-\frac{3Q}{5}=\frac{2Q}{5}\] [Using equation (i)]You need to login to perform this action.
