A mixture is a substance with a variable composition and is strong when the elements of that mixture bond to form a compound. Different compounds are air, coffee, tea etc... Coffee, for instance, can be weak or strong, and milk can be "whole" or low-fat. Though their molecular composition is variable, each of the mixtures described here is the same throughout: Such a mixture is described as homogeneous. Coffee is an example of a solution, a specific type of homogeneous mixture. Most homogeneous mixtures can be considered solutions.
Heterogeneous mixtures contain regions that differ from one another. As an example, a glass of cold tea with undissolved sugar at the bottom is a heterogeneous mixture: the tea at the top is unsweetened or even bitter, whereas at the bottom, there is an overly sweet sludge of tea and sugar, however, if you heat up the tea it can become homogeneous.

The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
