A) \[\text{/2}\]
B) \[\]
C) \[2\,\]
D) \[\text{3}\,\]
Correct Answer: B
Solution :
Efficiency of heat engine,\[\eta =1-\frac{{{T}_{2}}}{{{T}_{1}}}\] when temperature of source and sink are doubled, then efficiency, \[n=1-\frac{2{{T}_{2}}}{2{{T}_{1}}}=1-\frac{{{T}_{2}}}{{{T}_{1}}}\] \[\eta =\eta \]You need to login to perform this action.
