What is endothermic reaction ?

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}⋆$

A reaction in which heat is either absorbed from the surrounding or has to be supplied continuously from outside is called as endothermic reaction.

Some examples are :- Melting of ice, dissolution of potassium nitrate in water, heat from the surroundings is absorbed and therefore the temperature of the resulting solution is less.The process in which heat is absorbed from outside is called endothermic process
