AI overview

Boiling is the process where a liquid gets hot enough that it rapidly turns into vapor, creating bubbles that rise to the surface—you can see this happening in the image of water in an electric kettle. It matters because boiling is one of the most common ways people heat water for cooking, making tea and coffee, and sterilizing water to make it safe to drink.

Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation. Boiling occurs when a liquid is heated to its boiling point, so that the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. Boiling and evaporation are the two main forms of liquid vapourization.
