Clausius-Clapeyron equation

The Clausius-Clapeyron equation describes the relationship between the pressure and temperature of a substance as it changes from one phase to another, like from liquid to gas. It helps explain how boiling points change with pressure; for example, water boils at a lower temperature at higher altitudes where pressure is lower. This equation is essential in meteorology and engineering, assisting in understanding phenomena like cloud formation and evaporation. Overall, it illustrates the balance between heat energy, pressure, and phase changes of materials.
