Boiling vs. Evaporating — What's the Difference?
By Tayyaba Rehman — Published on October 5, 2023
Boiling is the process where a liquid turns into a vapor by heating it to its boiling point, often producing bubbles. Evaporating is the gradual change of a liquid into vapor at any temperature, usually at the surface.

Key Differences
Boiling is the phase transition that occurs when a liquid is heated to its boiling point, causing it to vaporize rapidly and usually form bubbles. Evaporating, on the other hand, is a slower process that occurs when liquid turns into vapor without necessarily reaching its boiling point.
In boiling, the entire volume of the liquid is involved, and you'll often observe bubbles forming and rising to the surface. Evaporating is typically a surface phenomenon, where the liquid slowly turns into vapor at the exposed surface without the formation of bubbles.
From a grammatical perspective, both "boiling" and "evaporating" function primarily as present participle forms of the verbs "to boil" and "to evaporate." However, "boiling" can also be a noun as in "the boiling of water," while "evaporating" is less commonly used as a noun.
Boiling is often an intentional act done for cooking, sterilization, or distillation, requiring an external heat source to reach the boiling point. Evaporating is a more natural process that occurs over time, often facilitated by environmental factors like heat and wind but doesn't necessarily require an external heat source.
