On the basis of kinetic theory explain why, ammonium chloride sublimes and goes from solid state directly into vapour state
Asked by anitabahuguna | 04 May, 2019, 09:57: PM
Expert Answer
When ammonium chloride absorbs heat then solid aprticleds filled with energy and this energy is sufficient to break its intermoleucal forces. So intermolecular distance increases  and solids are converted directly in gases. This transition from Solid to vapour is rapid. so it can be seen as direct Solid to gas transtion.
