A Carnot's engine used first an ideal monoatomic gas then an ideal diatomic gas. If the source and sink temperature are `411^(@)C and 69^(@)C` respectively and the engine extracts `1000 J` of heat in each cycle, then area enclosed by the `PV` diagram is

A Carnot engine used first ideal monoatomic gas and then an ideal diatomic gas , if the source and sink temperatures are 411^(@)C and 69^(@)C ,respectively and the engine extracts 1000 J of heat from the source in each cycle , then

For a carnot engine the source and the sink temperatures are 527^(@)C and 47^(@)C respectively and the engine extracts 800 J of heat in each cycle. What is the area enclosed by the P-V diagram in terms of energy units ?

A Carnot engine used first an ideal monoatomic gas (gamma = 5//3) and then an ideal diatomic gas (gamma = 7//5) as its working substance. The source and sink temperatures are 411^(@)C and 69^(@)C respectively and the engine extracts 1000 J of heat from the source in each cycle. then

A heat engine works between source and sink temperatures 150°C and 30°C respectively.The efficiency of heat engine may be

A heat engine works between source and sink temperatures 150°C and 30°C respectively.The efficiency of heat engine may be

A Carnot engine working in a cycle absorbs 10^4 calories. If the temperature of the source and the sink are 327^@C and 27^@C respectively, calculate the heat rejected to the sink.

A perfect Carnot engine utilises an ideal gas as the working substance. The source temperature is 227^circC and the sink temperature is 127^circC . Find the efficiency of the engine, and find the heat received from the source and the heat released to the sink when 10,000 J of external work is done.

A Carnot's engine operates with source at 127^(@)C and sink at 27^(@)C .If the source supplies 40 kJ of heat energy, the work done by the engine is
