A) 80 J
B) 400 J
C) 800 J
D) 160 J
E) 1600 J
Correct Answer: E
Solution :
As, efficiency\[\eta =1-\frac{{{T}_{2}}}{{{T}_{1}}}=1-\frac{300}{600}\] \[=1-\frac{1}{2}=\frac{1}{2}\] \[\therefore \] Output (work) \[=n\times \] heat energy supplied \[\Rightarrow \] \[800=\frac{1}{2}\times \Delta \,Q\] \[\Rightarrow \] \[\Delta Q=800\times 2=1600\,J\]You need to login to perform this action.
