Carnot engine, efficiency, equation of state, entropy, specific heat, Maxwell’s TdS relation, Van der Waal’s equation, Berthelot’s equation, Clausius’s equation.


The efficiency of Carnot engine, an important machine in classical thermodynamics, depends only on the temperatures of source and sink reservoirs and is independent of the nature of the working substance. There are several real gas equations which may be used to verify this statement. Here we choose three real gas equations viz. Van der Waal’s, Berthelot’s and Clausius’s real gas equation of state for simplicity for this verification.
