उत्तर
Yes, sublimation differs from evaporation.
In sublimation, a solid directly changes into a vapour without first becoming a liquid, and this occurs below its melting point. Substances like camphor and naphthalene show this behaviour.
In evaporation, a liquid turns into a vapour from its surface at temperatures below its boiling point.
Thus, sublimation is the direct change from solid to vapour, while evaporation is the change from liquid to vapour.
