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

The correct Answer is:
C
The freezing point of water `=0^(@)C=273K`
Boiling point of water `=100^(@)C=373K`
Efficiency of heat engine `eta-1-(T_(L))/(T_(H))=1-(273)/(373)=0.2681" "eta=26.8%`
