An ideal heat engine working between temperature `T_(1)` and `T_(2)` has an efficiency `eta`, the new efficiency if both the source and sink temperature are doubled, will be

A

`eta/2`

B

`eta`

C

`2eta`

D

`3eta`

Text Solution

Verified by Experts

The correct Answer is:
B
Since, `eta=1-(T_2)/(T_1)`, As `T_1` and `T_2` both double, no change.
