Carnot engine takes in a thousand kilocalories of heat from a eservoir at 627^@C and exhausts it to a sink at 27^@C .What is its efficiency ?How much work does it perform?Express it in kilowatt-hour

Carnot engine takes in a thousand kilocalories of heat from a eservoir at 627^@C and exhausts it to a sink at 27^@C .What is its efficiency ?How much work does it perform?Express it in electron-volt.

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 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
