👉 Azeotropy is a thermodynamic property of gases that refers to the phenomenon where gases at different temperatures have very similar densities. This property occurs in both gaseous phases and solid phases, but it's most commonly observed in liquids and solids. In liquid or gas phase, the temperature difference between them is so small that they can be considered equal, resulting in a uniform density of 1 for all molecules within each phase. Azeotropy plays an important role in many natural processes such
