Question:

Is sublimation different from evaporation? Justify. [Pg. No. 84]

Answer: Verified

Yes, sublimation is different from evaporation. Sublimation is the change of a substance directly from the solid state to the gaseous state without passing through the liquid state, as seen in camphor, iodine or ammonium chloride. Evaporation, on the other hand, is the change of a liquid into vapour from its surface at temperatures below its boiling point. Thus, sublimation involves a solid-to-gas change, while evaporation involves a liquid-to-gas change.
