Answer
63 %
Explanation:
It is given that the reservoirs is at the temperature of 627°C and 27°C
So lower temperature that is = 60°C=273+60=333 K
And the higher temperature that is = 627°C =273+627=900 K
We know that the thermal efficiency of thermal reservoir = 1- =
= 0.63 =63 %
So the efficiency of the reservoir is 63%
