A) \[3\times {{10}^{4}}J\]
B) \[5\times {{10}^{4}}J\]
C) \[6\times {{10}^{4}}J\]
D) \[7\times {{10}^{4}}J.\]
Correct Answer: B
Solution :
\[E=\frac{5}{2}nRT\] \[=\frac{5}{2}PV\] \[=\frac{5}{2}P\frac{m}{p}\] \[=\frac{5}{2}\times \frac{(8\times {{10}^{4}})(1)}{4}=5\times {{10}^{4}}J\] This question contains Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.
