The efficiency of a heat engine working between the freezing point and boiling point of water is

A

`6.25%`

B

`20%`

C

`26.8%`

D

`12.5%`

Text Solution

Verified by Experts

Freezing point of water `T_(L) = 0^(@)C` = 273 K
`:.` Efficiency, `eta = 1 - (T_(L))/(T_(H)) = 1- (273)/(373) = 0.2681 , eta = 26.8%`
