Difference Between Physical and Chemical Properties

Physical properties:

Table
  1. Physical properties:
  2. Chemical Properties:

Physical properties can be perceived and measured without any change in the composition of the substance. Physical properties are used to observe and describe the substance.

Chemical Properties:

Chemical properties are only observed in a chemical reaction and therefore 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 necessary to demonstrate the property

The chemical reaction is necessary to demonstrate the property

Physical properties are measured without changing the chemical structure of the substance

Chemical properties can be measured by changing the chemical composition of matter.

There is no direct association with the chemical bond of a material

This is directly associated with the chemical bonding of a material

The chemical identity remains the same

Changes in chemical identity

Without changing a subject's identity, you can measure

Can be measured by changing the identity of a substance

You can change physical condition but not molecules

It involves changes in molecules

Which depends or not on the amount of matter

It depends on the amount of substance.

Here are some examples of physical properties:

Molecular weight, color, texture, shape, hardness, malleability, smell, appearance, solubility, melting point, freezing point, boiling point, density, mass, viscosity, temperature, etc.

Here are some examples of chemical properties:

Toxicity, Reactivity, Viscosity, Chemical stability, Flammability, Half-life, Compressibility, Oxidation states, Heat of combustion, Type of chemical bonds, Radioactivity (of one atom, radiation emission), etc.
