A) \[(T-2.4)\,K\]
B) \[(T+4)\,K\]
C) \[(T-4)\,K\]
D) \[(T-2.4)\,K\]
Correct Answer: C
Solution :
\[\Delta U=\mu {{C}_{V}}\Delta T\] & \[0=W+\Delta U\] \[\Rightarrow \] \[\Delta U=-6\] \[(\because \,\,W=6R)\] Therefore \[-6R=1\left( \frac{R}{\gamma -1} \right)\,\,\Delta T=\frac{3}{2}R\Delta T\] \[\Rightarrow \]\[\Delta T=-4\] \[\Rightarrow \] \[{{T}_{final}}=(T-4)\,K\]You need to login to perform this action.
