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 1000J of heat in each cycle, then area enclosed by the PV diagram is

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

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 ?
