A carnot engine operates between temperatures `T` and `400K(Tgt400K)`. If efficiency of engine is `25%`, the temperature `T` is :

A

`400 K`

B

`500 K`

C

`533.3 K`

D

`600 K`

Text Solution

Verified by Experts

The correct Answer is:
C
`eta_(("efficiency")) =(T_(2)-T_(1))/(T_(2))`
or `0.25=(T-400)/T`
`:. T=533.3 K`
