A heat engine works on a carnot cycle with a heat sink of `27^(@)C`. The efficiency is 10%. The temperature of source is

A

270K

B

30K

C

`60^(@)C`

D

`30^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
`0.1=1-(300)/(T_(1))`
`(300)/(T_(1))=0.9`
`T_(1)=(3000)/(9)=333K`
`t_(1)=333-273`
`=60^(@)C`.
