An ideal heat engine is working between ...

An ideal heat engine is working between temperature `T_(1) and T_(2)` has efficiency `eta`. If both the temperatures are raised by `100^(@)k` each, the new efficiency will be :

A

`eta`

B

less than `eta`

C

more than `eta`

D

cannot be perdicted.

Text Solution

Verified by Experts

The correct Answer is:
B
Efficiency decreases as temperature of sink is more effective.
Thus, correct choice is (b).
