A scientist says that the efficiency of his heat engine which operates at source temperature `127^(@)C` and sink temperature `27^(@)C is 26%`, then

A

It is impossible

B

It is possible but less probable

C

It is quite probable

D

Data are incomplete

Text Solution

Verified by Experts

The correct Answer is:
A
`eta_(max) = 1 -(T_(2))/(T_(1)) = 1-(300)/(400) = (1)/(4) = 25%`
So `26%` efficiency is impossibel
