Which one of the following is the best definition of evaporation?Evaporation is a type of separating technique used to remove a liquid from a solution leaving the soluble solids.Evaporation is a type of separating technique used to separate an insoluble solid from a liquid.Evaporation is a type of separating technique used to separate mixtures of substances that are soluble in the same solvent.Evaporation is a type of separating technique used to separate a solvent from a solution.

Identify the best description of the difference between evaporation and distillation.Distillation involves evaporation, but the solvent is collected as well as the soluteEvaporation involves distillation, but the solvent is collected as well as the soluteDistillation involves evaporation, but only the solute is collectedEvaporation and distillation are unrelated methods of separation
