A) \[200{}^\circ C\]
B) 500K
C) 700K
D) \[127{}^\circ C\]
Correct Answer: B
Solution :
\[\therefore \,\,\text{ }Here\text{ }{{Q}_{2}}={{Q}_{1}}-W\,\,=\,\,120\text{ }J\] \[\because \,\,\,\text{ }\frac{{{Q}_{2}}}{{{Q}_{1}}}=\frac{{{T}_{2}}}{{{T}_{1}}}\] \[\frac{120}{200}=\frac{300}{{{T}_{1}}}\] \[{{T}_{1}}\,\,=\,\,\frac{300\times 200}{120}\,\,=\,\,500\,\,K\]You need to login to perform this action.
