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.
