A Carnot engine absorbs 750 J of heat energy from a reservoir at `137^(@)C` and rejects 500 J of heat during each cycle then the temperature of sink is

A

`0.25^(@)C`

B

`0.34^(@)C`

C

`0.44^(@)C`

D

`0.54^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B

Here `T_(1)=273+173=410, Q_(1)=750 J , Q_(2)=500 J`
As, `(Q_(2))/(Q_(1))=(T_(2))/(T_(1))`
`rArr T_(2) =(Q_(2))/(Q_(1))(T_(1))=(500)/(750)xx410`
=273.34 K = 237.34-273 = `0.34^(@)C`
