Question

The Carnot heat engine received heat Q₂ = 100 J from a heat reservoir of temperature T₂ = 600 K, performed work, delivered heat −Q₁ to the cooler reservoir of temperature  T₁ = 300 K, and returned to the initial state. Calculate the engine’s efficiency, the performed work and the supplied heat and the change in internal energy, Prove that Generally the Carnot engine efficiency can never equal one.                                                                                               [10]
