The efficiency of an ideal heat engine working between the freezingpoint 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

Efficiency of ideal heat engine, `eta=(1-(T_(2))/(T_(1)))`
`T_(2)` : Sink temperature
`T_(1)`: Source temperature
`% eta=(1-(T_(2))/(T_(1)))xx100`
`=(1-(273)/(373))xx100`
`=((100)/(373))xx100=26.8%`
