Background Information

Physical properties of matter are those that can be observed without changing the chemical composition of the matter. Size, shape, color, flexibility, texture, solubility, melting point, and odor are just a few physical properties. Using these observations is helpful in classifying matter and determining which materials would be ideal for various uses. For example, something that dissolves in water would not be useful in making beverage cups.
