A carnot engine working between 300K and 400K has 800 j of useful work . The amount of heat enegy supplied to the engine from the source is

A

2400 J

B

3200 J

C

1200 J

D

3600 J

Text Solution

Verified by Experts

The correct Answer is:
B
`eta=1-(T_(2))/(T_(1))andeta=(W)/(Q_(1))implies(W)/(Q_(1))=1-(T_(2))/(T_(1))`
`(800)/(Q_(1))=1-(300)/(400)`
`Q_(1)=3200J`
