Question

Differentiate between sublimation evaporation and boiling.

Answer 1

Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gaseous phase before reaching its boiling point.

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point.
