A) \[\frac{2}{3}\]K
B) \[\frac{3}{2}\]K
C) 1 K
D) 2 K
Correct Answer: A
Solution :
\[w=-\int{{{P}_{ext}}dV}\] \[=-\,4\left( 1-5 \right)=16\text{ }J\] \[\Delta U=0\] for isothermal process (ideal gas) \[\therefore \,\,\,\,q=-w\] \[\therefore \,\,\,q=-16\,J\And \,\,\left| q \right|=nCv\Delta T\] \[\left| -16 \right|=1\times 24\times \Delta T\] \[\therefore \,\,\Delta T=\frac{2}{3}K\]You need to login to perform this action.
