Evaporation, Vapour pressure and Boiling Kya Hai? Evaporation Kya Hai? Evaporation is the “spontaneous escape of molecules from a liquid surface at any temperature.” It occurs at all temperatures and is a surface phenomenon. At any temperature, the energy of the molecules in a liquid is not equal, and this causes them to flow at …
