Clapeyron equation

The Clapeyron equation describes the relationship between pressure, temperature, and phases of a substance, such as solid, liquid, or gas. It helps explain how different states of matter coexist and transition into one another, particularly during phase changes like melting or boiling. The equation relates the change in pressure to the change in temperature for a phase transition, providing a way to predict how a substance behaves under varying conditions. Essentially, it helps scientists understand and calculate how a material will react when subjected to changes in temperature and pressure.
