Answer 2

Explanation:

An exothermic reaction occurs when the temperature of a system increases due to the evolution of heat. An example of an exothermic reaction is the mixture of sodium and chlorine to yield table salt.

An endothermic reaction occurs when the temperature of an isolated system decreases while the surroundings of a non-isolated system gain heat.Photosynthesis is an example of an endothermic chemical reaction.
