The reaction in which heat and light are liberated is called endothermic reaction.
Exothermic reaction
The reaction in which heat and light are liberated is called an exothermic reaction.
Example: Burning of Coal, fuel etc.
While reaction in which heat is given to the reactants to form the products are called endothermic reactions. Melting of solid salts and ice cube to water are examples of endothermic reactions.
