A) work done by gas is \[{{10}^{5}}J\]
B) work done on gas is \[{{10}^{5}}J\]
C) work done by gas is \[0.5\times {{10}^{5}}J\]
D) work done on the gas is \[0.5\times {{10}^{5}}\text{ }J\]
Correct Answer: D
Solution :
[d] \[dU=dQ-dW=\left( 8\times 105-6.5\times 105 \right)\] \[=1.5\times {{10}^{5}}J\] \[dW=dQ-dU={{10}^{5}}-1.5\times {{10}^{5}}\] \[=-0.5\times {{10}^{5}}\] \[-\]ve sign indicates that work done on the gas is \[0.5\times {{10}^{5}}J\]You need to login to perform this action.
