Study Notes
Physical and chemical properties are two distinct categories of properties that can be observed or measured for substances. Physical properties include color, density, hardness, and melting and boiling points, and are not changed by chemical changes[2-4] Physical properties are intensive properties, as their ratio does not depend on the amount of matter present Chemical properties, on
