A) 800 J
B) 1600 J
C) 3200 J
D) 6400 J
Correct Answer: B
Solution :
The efficiency of Carnot engine is given by Given \[{{T}_{1}}=600\,K,\] \[{{T}_{2}}=300\,K\] \[\therefore \] \[n=1-\frac{300}{600}\] \[\Rightarrow \] \[n=1-\frac{1}{2}\] \[\Rightarrow \] \[n=\frac{1}{2}=50%\] Also, \[n=\frac{W}{Q}=\frac{800}{Q}=\frac{1}{2}\] Thus, \[Q=800\times 2=1600\,J\]You need to login to perform this action.
