An ideal gas heat engine operators in a ...

An ideal gas heat engine operators in a carnot's cycle between `227^(@)C` and `127^(@)C`. It absorbs `6xx10^(4)J` at high temperature. The amount of heat converted into work is …………… .

A

`2.4xx10^(4)J`

B

`4.8xx10^(4)J`

C

`1.2xx10^(4)J`

D

`6xx10^(4)J`

Text Solution

Verified by Experts

The correct Answer is:
c

`(W)/(Q)=1-(T_(2))/(T_(1))`
`W=(1+(273+127)/(273+227))xx6xx10^(4)=1.2xx10^(4)J`
