Nonequilibrium thermodynmics with thermodynamic parameter of lifetime of system. I

TL;DR

This paper introduces a new thermodynamic parameter called system lifetime to describe nonequilibrium states, providing statistical distributions, thermodynamic relations, and explicit expressions for thermal conductivity, highlighting how flows affect system lifetime.

Contribution

The paper proposes the concept of system lifetime as a thermodynamic parameter and derives related statistical and thermodynamic relations, extending existing nonequilibrium thermodynamics frameworks.

Findings

Flows can only reduce the average system lifetime near equilibrium.

Explicit expressions for average lifetime and conjugate quantities are obtained for thermal conductivity.

Possibilities exist to increase the average lifetime of the system.

Abstract

To describe the nonequilibrium states of the system, a new thermodynamic parameter - system lifetime - is introduced. Statistical distributions that describe the behavior of energy and lifetime are recorded. Entropy and obtained thermodynamic relations are compared with the results of Extended Irreversible thermodynamics, where as an additional parameter selected fluxes. For the case of thermal conductivity explicit expressions are obtained for average lifetime and conjugate thermodynamic quantity. It is shown that near the equilibrium state, when is only one stationary nonequilibrium state, flows can only reduce the average system lifetime. But there are possibilities to increase the average lifetime of the system.
