Title: Demonstrate Sublimation using ammonium chloride
Sublimation is a process in which a solid changes directly into vapours without passing through liquid state.
Common substances which can sublime are ammonium chloride, naphthalene, iodine, camphor and menthol.
Only those solids sublime which heave an appreciable vapour pressure in the solid state at room temperature.
