Difference between Physical and Chemical change
Physical change |
Chemical changes |
The changes occurs in the physical properties of matter is called physical change. |
The changes occurs in the chemical properties of matter is known as chemical changes. |
Physical changes does not change the chemical composition of matter. |
Chemical change bring out the changes in chemical composition of matter. |
Physical changes are mostly reversible process. |
Chemical process are mostly Irreversible. |
In the physical changes new products does not form. |
In the chemical changes new products are form. |
Some physical changes occurs when the substance is heated or cooled. |
Chemical changes occurs when there is absorption or release of energy. |
The chemical bonds does not affect by the physical changes. |
The chemical bonds are Directly affect by the chemical change. |
The chemical properties does not change in it hence these are retained. |
The new products formed have new chemical properties from the original substances. |
The physical changes are temporary. |
The chemical changes are permanent. |
The example for physical changes Is–conversion of ice into vapours. |
The example for the chemical change is –rusting, cooking of food etc. |
