Physical properties of matter are those that can be observed without the matter undergoing a chemical change (change in composition). Examples of physical properties are color, solubility in water or another solvent, temperature, volume, mass and density. Melting and boiling points are also physical properties. They are related to physical changes, not chemical changes. The physical properties of a substance are those you observe with your senses.
Chemical properties can only be observed when a substance undergoes a chemical reaction. Examples of chemical properties are flammability, tendency to corrode, and tendency to react with acid.
Both chemical and physical properties of matter can be further described as intensive or extensive. An intensive property depends on the amount present, such as mass or volume. An extensive property is independent of the amount of the substance present, such as color or density.
