The differences are:
1. Physical change is easily reversible while chemical change is not easily reversible
2. Physical change forms no new substance. while chemical change forms new substance
3. In Physical change there is no change in the mass of a substance involved while In chemical change, there is a change in the mass of the substance involved.
4. Physical change does not involve great heat. while chemical change involves considerable amount of heat.
The Similarities are :
1. They can be both reversible.
2. Heat is involved
3. They both involve reasonable amount of substance or matter.
Physical properties exhibit physical changes such as:
boiling and melting point of a substance, density, hardness, malleability, crystalline form and some properties that can be detected by our sense organ, such as taste, color and odor.
While chemical properties occur when matter or substance undergoes a change to form another new substance. For example : rusting of iron and burning of wood.
