    Highlights of general thermodynamic relations If f(x,y,z) =0 then (i) (∂x/∂y)z (∂y/∂z)x(∂z/∂x)y = –1 (∂y/∂x)z(∂x/∂y)z=(∂y/∂z)x(∂z/∂y)x =(∂z/∂x)y(∂x/∂z)y=1 Z=z(x,y), y =y(z,x) and x=x(y,z) If z = z(x,y) then dz = (∂z/∂x)y dx + (∂z/∂y)x dy For a continuous function ∂2z/∂x∂y =∂2z/∂y∂x Internal energy(U), Helmholtz energy (A), enthalpy (H) and Gibb’s free energy(G) are characteristic functions in thermodynamics.These […]

    HIGHLIGHTS OF AVAILABILITY

    HIGHLIGHTS OF AVAILABILITY  Availability is the maximum theoretical work which can be obtained by a heat engine. Since some heat is rejected in a heat engine, therefore recovery of maximum work is not possible. The work which cannot be recovered because of heat rejection to the surroundings is the unavailability. When heat is added to […]

    THERMODYNAMIC POTENTIALS AND THERMODYNAMIC PARAMETERS—SHEET 2—–Euler’s Law of Reciprocity  

    THERMODYNAMIC POTENTIALS AND THERMODYNAMIC PARAMETERS—SHEET 2—–Euler’s Law of Reciprocity     Thermodynamic potentials are useful in the thermodynamics of chemical reactions. These potentials also describe the non-cyclic processes. They are four thermodynamic potentials. These are internal energy, the enthalpy, the Helmholtz free energy and the Gibbs free energy. All the thermodynamic potentials are energy terms. These potentials cannot be  […]
