HOPE IT HELPS YOU
Explanation:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
Answer:
Such changes which do not produces any new substances after the reaction is called as the physical change, whereas the changes which bring out the formation of new substance is named as the chemical change. So we can say that the main difference lies in the chemical composition, where one (chemical change) of the change is involved in altering the composition of the material and thus forms new substance and the other (physical change) brings out alteration in size, shape and colour only.
