Difference between Physical and Chemical Properties

Substances have their characteristics and properties through which we can recognize and classify them. The classification includes the physical and chemical properties of a particular matter.

Physical properties:

Physical properties can perceive and measured without any changes in the substance composition. Physical properties are utilized to observe and describe the substance.

Chemical properties:

Chemical properties are observed only throughout a chemical reaction and thus the matter changes the chemical composition.

Here are some points of difference between physical properties and chemical properties.

Physical properties	Chemical properties
No chemical reaction is required to demonstrate the property	The chemical reaction is required to demonstrate the property
Physical properties are measured without modifying in the chemical structure of the substance	Chemical properties can be measured by modifying the chemical composition of a matter.
There is no direct associate to the chemical bond of a matter	This is direct associate to the chemical bond of a matter
Chemical identity remains the same	Chemical identity changes
Without changing the identity of a matter it can be measured	Can be measured by changing the identity of a substance
It can change the physical condition but not the molecules	It involves the molecule changes
Whether or not depend on the quantity of the matter	It depends on the quantity of the substance.
Some examples of  physical properties include: Molecular weight, Color, Texture, Shape Hardness, Malleability, Odor, Appearance, Solubility, Melting point, Freezing point, Boiling point, Density,  Mass, Viscosity, Temperature, etc.	Some examples of chemical properties include: Toxicity, Reactivity, Viscosity, Chemical stability Flammability, Half-life, Compressibility, Oxidation states, Heat of combustion, Types of chemical bonds, Radioactivity (from an atom, emission of the radiation), etc.
