How does evaporation occur?
That's the process called evaporation. … It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy.
Does boiling occur throughout a liquid?
Evaporation happens only at the surface of a liquid and occurs at any temperature (so long as the substance is a liquid at that temperature). … Boiling, on the other hand, happens throughout the bulk of a liquid, usually starting from some site on the inside of the container and rising in a bubble to the surface.
