Explanation:

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. (Heat is absorbed)

Example- Melting ice cubes, Melting solid salts,  Evaporating liquid water.

An exothermic reaction is a chemical reaction in which less energy is needed to break bonds in the reactants than is released when new bonds form in the products. (Heat is released)

Example- Burning of a candle, Rusting of iron, freezing of water.
