An ideal gas heat engine operates in Carnot cycle between `227^(@)C` and `127^(@)C`. It absorbs `6 x 10^(4) cals` of heat at higher temperature. Amount of heat converted to work is

A

`2000 J`

B

`4000 J`

C

`8000 J`

D

`5600 J`

Text Solution

Verified by Experts

The correct Answer is:
a
Efficiency , `eta = 1 - T_(2)/T_(1)`
` = 1 - ((127 + 273))/((227 + 273)) = 1 - (400)/ (500) = 1/5 `
` :. ` The amount of heat converted into work,
` W = eta Q_(1) = 1/5 xx 10^(4) = 2000 J `
` rArr W = 2000 J `
