27. The efficiency of a Carnot engine betwe
HTR at T, and LTR at T2 is given by:
a) 1
T
1 -
T.
b) T-T
ITT
TI-T
T
d)
Ti-T
2.
T​

Answer 1

For carnot engine-

η(efficiency)=1−

T

H

T

L

T

H

= high temperature (sources)

T

L

= low temperature(sink)

For same efficiency, ratio of temperature should remain same.
