A carnolt engine works between `27^(@)C` and `127^(@)C` . Heat supplied by the source is 500 J . Then heat ejected to the sink is :

A

1000 J

B

667 J

C

375 J

D

500 J

Text Solution

Verified by Experts

The correct Answer is:
C
`(Q_("in"))/(Q_("out")) =(T_("in"))/(T_("out"))`
`rArr (500)/(Q_("out")) `
`rArr (500)/( Q_("out")) =(400)/(300) rArr Q_("out")=375 J`
