A Carnot engine operating between two reservoirs has efficiency 
. When the temperature of cold reservoir raised by x, its efficiency decreases to 
. The value of x, if the temperature of hot reservoir is 99° C, will be:
Text Solution
Verified by ExpertsThe correct answer is:
D
T H = 99°C = 99 + 273 = 372 K
___
= 2 x 124 = 248 K
248 + X = 5 x 62
X=310-248 = 62K
