Solid - Vapour Equilibrium

The video tutorial explains the sublimation process of solid iron in a closed vessel, where violet vapors emerge and eventually reach a constant intensity, indicating an equilibrium state. This process involves the direct conversion of solid iron into vapor, forming iron vapor. The tutorial also highlights the equilibrium between solid and gaseous iron, represented by a double-headed arrow. Additionally, examples of solid vapor equilibrium, such as ammonium chloride and chamfor, are provided.
