For a carnot engine, source temperature is `527^0 C` and sink at `200 K`.If 12kJ of work is done then heat absorbed is?

Efficiency of carnot heat engine,if source temperature is T1K and sink temperature is T2K

In a Carnot engine , the temperature of the reservoir is 927^@C and that of sink is 127^@C . If the work done by the engine when it transfers heat from the reservoir to sink is 12.6xx10^6 J . the quantity of heat absorbed by the engine from the reservoir is

A carnot's engine works between a source at a temperature of 27^(@)C and a sink at -123 ^(@)C . Its efficiency is

A carnot engine whose source temperature is at 400 K takes 100 kcal of heat at this temperature in each cycle and gives 70 kcal to the sink. Calculate (i) the temperature of the sink and (ii) the efficiency of the engine.

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