The Clausius-Clapeyron Equation review
BRIEF HISTORY The Clausius-Clapeyron equation is a differential equation that describes the interdependence of pressure and temperature along a pure substance’s phase equilibrium curve. Clapeyron proposed this equation in 1834, and R. Clausius made improvements to it in 1850. In honor of Rudolf Clausius and Benoît Paul Émile Clapeyron, the Clausius Clapeyron equation is a way of explaining a discontinuous phase transformation between two phases of matter of a single constituent. There is no direct relationship between a liquid’s temperature and vapor pressure. The equation may also be referred to as the Clapeyron equation or the Clapeyron-Clausius equation.
