Evaporation is a surface phenomenon why
WebAug 16, 2015 · The temperature at which liquid changes into its gaseous state is called as boiling point. During boiling of a liquid, say water or milk, heating is to be done from the bottom of the vessel to bring the temperature of the entire liquid to its boiling point - so it is a bulk phenomenon. WebDec 31, 2024 · Conversely, evaporation is surface phenomena, which take place only on the surface of the liquid. Boiling of a liquid occurs only at the boiling point of that liquid, i.e. it takes place only at a definite …
