PHYSICAL REACTIONS

Changes that affect only the physical property of a substance and where no new substances are formed are called physical reactions.

CHEMICAL REACTIONS

A chemical reaction is a process in which new substances are formed.
The substances that are present initially, that undergo a chemical reaction are called reactants.
The substances that are formed as a result of the chemical reaction are called products.

eg. Burning of wax.
