The source tempreature of a Carnot engine is `127^(@)C`. It takes 500 cal of heat from the source and rejects 400 cal to the sink during each cycle. What is the temperature of the sink ?

A

`37^(@)C`

B

`47^(@)C`

C

`20^(@)C`

D

`27^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B

`thereforeQ_(2)/Q_(1)=T_(2)/T_(1)`
`thereforeT_(2)=(Q_(2)/Q_(1))T_(1)=(400/500)xx400`
`=320K=(320-273)=47^(@)C`
