In a Carnot engine , the temperature of the reservoir is `927^@C ` and that of sink is `127^@C` . If the work done by the engine when it transfers heat from the reservoir to sink is `12.6xx10^6 J` . the quantity of heat absorbed by the engine from the reservoir is

A

`16.8 xx 10^6` J

B

`4 xx 10^6` J

C

`7.6 xx 10^6` J

D

`4.2 xx 10^6` J

Text Solution

Verified by Experts

The correct Answer is:
A
`eta=1-(T_2)/(T_1)=(W)/(Q_1)`
`implies (12.6xx10^6)/(Q_1)=1-((27+273))/((927+273))`
`implies Q_1=Wxx4/3=12.6 xx10^6 xx 4/3=16.8xx10^6J`
