Answer 1

Endothermic reaction are those in which heat energy is absorbed. It causes fall in temperature.
Exothermic reactions are those in which heat energy are released. It causes rise in temperature.

Answer 2

The difference between endothermicand exothermic reactions lies in the words themselves. "Thermic" refers to heat, just as in the word "thermometer." "Exo" means "outside" and "endo" means "inside." Thus, an endothermic reaction pulls heat into an object or area, while an exothermic reactionexpels heat.
