A) \[600K,400K\]
B) \[400K,200K\]
C) \[500K,300K\]
D) \[300K,100K\]
Correct Answer: D
Solution :
: Efficiency of Carnots engine, \[\eta =1-\frac{{{T}_{2}}}{{{T}_{1}}}=\frac{{{T}_{1}}-{{T}_{2}}}{{{T}_{1}}}\] where \[{{T}_{1}}\] and \[{{T}_{2}}\] be the temperatures of source and sink respectively. In all four cases, \[{{T}_{1}}-{{T}_{2}}=200K\]. Therefore, 11 is maximum when 7i is minimum.You need to login to perform this action.
