All endothermic reactions produce heat and make surroundings warm. true false

The statement is False.

Explanation:

Endothermic reactions absorbs heat and make surrounding temperature low. The reaction which produces heat and make surroundings warm is called the exothermic reaction. Exothermic reactions produce heat. In Endothermic reactions, molecular bonds gets broken and new molecular bonds may possibly form. So energy is needed to be stored in these bonds, so through endothermic reactions, surrounding energy is absorbed in the bonds and the temperature of the surroundings drops.

False

Explanation:

endothermic reactions do not produce heat, they only absorb heat from the surrounding. Exothermic reactions produce heat.
