Science Background:

·         Liquids have characteristic properties based on the molecules they are made of.

·         The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.

·         Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.
