Endothermic reactions are those in which heat is absorbed from the surroundings.

What are endothermic reactions?

They are reactions in which heat is absorbed from the surrounding, making the reaction vessels become colder.

It is unlike exothermic reactions in which heat is released into the surrounding, making the reaction vessel to be warmer.

For endothermic reactions, the enthalpy change is always positive because heat is absorbed. It is however negative for exothermic reactions because heat is evolved.
