Properties of matter help us identify substances. For example, in the picture above you see how salt and sugar dissolve in water. Using that a reference we can definitely say that Cup A is neither salt nor sugar. We know that cup B contains sugar, because gfiuef.vjsdbv. We also know that cup C conatains salt becausek c.kjhf;oihvjknaf;oihew'ofih.
