All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.
Some of these characteristics are common to all forms of matter and are therefore recognized as general properties. Others differ by the group and are known as particular properties. Some, too, are different even within the same group for each of the substa n ces that are part of it, considering specific properties.

Difference between chemical and physical properties: chemical: physical: chemical properties are properties that can be observed or measured when a substance undergoes a chemical change. Physical properties are properties that can be observed without bringing a chemical change. A chemical reaction needs to be conducted to show the property.
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
