When a liquid evaporate O the temperature of the substance increases O the temperature of the substance decreases O heat energy leaves the substance O heat energy enters the substance
Solution
Heat energy enters the substance is the correct option.
Molecules or atoms of the liquid are bound to each other because of an attraction--the form of this attraction can be many and quite complicated sometimes, but it\'s an attraction nevertheless. To overcome this attraction, the molecules or atoms must have a certain energy -- and this energy must be higher than the average energy of a molecule, otherwise the sample would evaporate instantaneously.
