Substances have properties and characteristics by which we can identify and thus classify them. Two of the broad classifications of these would include the chemical and physical properties of a particular substance.

Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.

Chemical properties are only observed during a chemical reaction and thus changing the substance's chemical composition.

Perhaps the best way to distinguish between the two is by examples. Examples of physical properties would include freezing, melting, and boiling points, density, mass, and volume. Examples of chemical properties include heat of combustion, reactivity with other chemicals, flammability, and types of bonds that will form.

Chemical property is associated with chemical change- which means the change happens only with a chemical reaction.

Physical property is associated with physical change- which menas that the change is very evident with the five senses.

Physical properties include properties that you can observe with your senses: such as a shape, color, size, mass, temperature.

Chemical properties are properties associated with a chemical change. Chemical properties such as re activity, heat of combustion, re activity to water, PH, malleability;  they determine the reaction that will occur during the chemical reaction.

Physical property is a property which describes a substance. For example: shape, height, color, melting point

Chemical property is a property which is associated with a chemical change. For example: reactivity, combustivity, burning

chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.Simply, chemical properties cannot be determined just by viewing or touching the substance.

physical property is any propery that is measurable whose value describes a state of a physical system. Physical properties are often referred to as observables.Physical properties are often characterized as intensive and extensive properties.

A chemical property and a physical property are related to chemical and physical changes of matter.
 
A physical propertyis an aspect of matter that can be observed or measured without changing it. Examples of physical properties include color, molecular weight and volume.

A chemical property may only be observed by changing the chemical identity of a substance. This property measures the potential for undergoing a chemical change. Examples of chemical properties include reactivity, flammability and oxidation states.
