A Carnot engine absorbs 300 cal of heat from a reservoir and rejects 250 cal of heat at 300 K during each cycle. Calculate:
The temperature of reservoir.

A Carnot engine absorbs 300 cal of heat from a reservoir and rejects 250 cal of heat at 300 K during each cycle. Calculate: The efficiency of engine.

A heat engine operating between 227^(@)C and 77^(@)C absorbs 10 kcal of heat from the 227^(@)C reservoir reversibly per cycle. Calculate total work done (in kcal) in two cycles.

A Carnot heat engine working between 27^@ C and 127@ C takes up 800 J of heat from the reservoir in one cycle.The work done by engine is :

A carnot engine works between 600 K and 300 K. In each cycle of operation, the engine draws 1000 J of heat energy from source. The efficiency of the engine is

If liquefied oxygen at 1 atmospheric pressure is heated from 50K to 300k by supplying heat at constant rate. The graph of temperature vs time will be

Consier a Carnot's cycle operating between T_1 = 500 K and T_2 = 300 K producing 1 k J of mechanical work per cycle. Find the heat transferred to the engine by the reservoirs.
