Evaporation is a method of separating a solvent (like water) from a solution by heating until the solvent turns into vapor and leaves behind the solute.During this process, the mixture stays mostly still—you don't stir or move it around much.It’s commonly used to obtain salts from a saltwater solution or to remove water from a sugar syrup.Since there's minimal movement or mixing, the solution’s composition remains stable while the solvent slowly evaporates.
