    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 […]
