Endothermic and Exothermic Reactions

Exothermic reactions are a type of chemical reaction that release heat as a part of the reaction. Heat escapes the reaction and is lost to the surroundings of the reaction therefore warming the surroundings. In an EXothermic reaction heat is EXiting. If an exothermic reaction were happening in a test tube and you were to touch the test tube after the reaction was done it would feel warm.

 

Endothermic reactions are a type of chemical reaction that must somehow take in heat for the reaction to take place. If an endothermic reaction were happening in a test tube and you were to touch the test tube after the reaction was done it would feel cold.
