This document summarizes different types of matter: elements, compounds, homogeneous mixtures, and heterogeneous mixtures. It provides examples for each category. Tin is described as an element. Water and salt are given as examples of compounds made of two or more chemically combined elements. Sugar water and corn oil are classified as homogeneous mixtures that maintain the same properties when combined. Tea and cupcakes are identified as heterogeneous mixtures made of two or more distinct substances that do not dissolve to form a new uniform substance.
