371328 If the source and sink temperature are \(411^\circ C\) and \(69^\circ C\) respectively and the engine extracts \(1000\;J\) of heat in each cycle, then area enclosed by the PV diagram is

1 \(300\;J\)
2 \(100\;J\)
3 \(700\;J\)
4 \(500\;J\)
PHXI12:THERMODYNAMICS

371329 In a heat engine, the temperature of the working substance at the end of the cycle is

1 Equal to that at the beginning
2 More than that at the beginning
3 Less than that at the beginning
4 Determined by the amount of heat rejected at the sink
PHXI12:THERMODYNAMICS

371330 If the temperature of the sink is decreased, the efficiency of heat engine

1 First increases then decreases
2 Increases
3 Decreases
4 Remains unchanged
PHXI12:THERMODYNAMICS

371331 Heat engine rejects some heat to the sink. This heat

1 Is unavailable in the universe
2 Converts into electrical energy
3 Converts into light energy
4 Converts into electromagnetic energy
