Why is it that endothermic reactions decrease in temperature?

Question

If endothermic reactions gain heat, shouldn’t their temperature increase?

In: Chemistry

Answer 1

Exothermic/endothermic depends on whether or not the temperature of the *environment* increases or decreases. If a reaction increases the temperature of the environment, it is exothermic. If the reaction reduces the temperature of the environment, it is endothermic.
