## Clausius–Duhem inequality

The **Clausius–Duhem Duhem** inequality [ 1 ] [ 2 ] is a way of expressing the second law of thermodynamics that is used in continuum mechanics . This inequality is particularly useful in determining whether the constitutive relation of a material is thermodynamically allowable. [ 3 ] This

## Clausius–Clapeyron relation

The **Clausius–Clapeyron** relation , named after Rudolf **Clausius** and Benoît Paul Émile Clapeyron , who defined it sometime after 1834, is a way of characterizing a discontinuous phase transition between two phases of matter. On a pressure – temperature (P–T) diagram, the line separating

## Thermodynamic equations

definition for power : During the latter half of the 19th century, physicists such as Rudolf **Clausius** , Peter Guthrie Tait , and Willard Gibbs worked to develop the concept of a thermodynamic system and the correlative energetic laws which govern its associated processes. The equilibrium
