Difference between Physical and Chemical change

Definition of Physical Change:
Physical change is a method in which the substance encounters changes in its physical properties, for example, appearance, shape, color, size, etc. With which no change has been made in their molecular composition.
Definition of Chemical Change:
The chemical change is characterized as the procedure in which the particles or atoms are modified or added to form another new substance. When a matter passes through chemical changes, then the chemical properties of the substance change and it changes with different chemical composition into a different substance. Bubble formations, energy development, changes in temperature, changes in odor are few signs of chemical change.
Here are some points of difference between a physical change and chemical change. 

Physical Change
Chemical Change
Physical change is reversible
Physical change is irreversible
It is a process of temporary change
It is a process of permanent change.
Energy is not absorbed and developed in the process of physical change.
During the reaction of chemical change, energy absorption and development occurs.
It involves changes in the physical properties of that substance, i.e. Color, size,  shape, etc.
It involves changes in the substance, chemical properties, and composition.
In this process, the original matter is being able to be recovered
In this process, the original matter cannot able to be recovered
The new product is not formed in this process.
The new product is produced by this process.
