A) \[\frac{2}{3}Q\]
B) \[\frac{3}{5}Q\]
C) \[\frac{2}{5}Q\]
D) \[\frac{1}{5}Q\]
Correct Answer: A
Solution :
For monoatomic gas at constant pressure \[\frac{\Delta U}{Q}=\frac{1}{3}\]or\[\Delta U=\frac{Q}{3}\] Now, applying first law of thermodynamics \[W=\Delta Q-\Delta U\] \[=Q-\frac{Q}{3}=\frac{2Q}{3}\]You need to login to perform this action.
