Abstract: This chapter discusses extended nonequilibrium thermodynamics. Nonequihbrium thermodynamics is based on the local-equihbrium hypothesis that allows the classical thermodynamics formulations to be valid at local state. The formulations include the Gibbs equation, thermodynamics potentials, stability conditions, and equations of state. The local thermodynamic equilibrium hypothesis has provided useful formalism with a unifying power, and led to useful predictions and interpretations of transport coefficients. Extended nonequilibrium thermodynamics uses the conserved variables and nonconserved dissipative fluxes as the independent variables to establish evolution equations for the dissipative fluxes satisfying the second law of thermodynamics. For the generalized entropy with the properties of additivity and convex function considered, extended nonequilibrium thermodynamics provides a more complete formulation of nonequilibrium thermodynamics and nonequilibrium equations of state. Gradients are also included in the formulation; it can relate microscopic phenomena to a macroscopic thermodynamic interpretation by deriving the generalized transport laws expressed in terms of the generalized frequency and wave-vector dependent transport coefficients.
