The definition of boiling is the process of violent vaporization on the surface and inside of a liquid at the same time. Boiling can only occur at a certain temperature. This temperature is called the boiling point, which increases as the external pressure increases.

The difference and connection between evaporation and boiling

The connection between evaporation and boiling: they are both two ways of vaporizing liquids, that is, they are both vaporization phenomena, and the liquid is in the process of evaporation and boiling

Both need to absorb heat.

The difference between evaporation and boiling: (1) Evaporation is a vaporization phenomenon that can occur in a liquid at any temperature, while boiling can only occur in a liquid at a certain temperature

(boiling point) The vaporization phenomenon; (2) Evaporation is a slow vaporization phenomenon that only occurs on the liquid surface, while boiling is a violent vaporization phenomenon that occurs both on the liquid surface and inside.
