Understand that an exothermic chemical reaction is one that releases energy to its surroundings.
Recall the common forms of energy that can be released during chemical reactions: heat, light, sound, and electrical energy.
Recognize that the most typical form of energy released in exothermic reactions is heat, which increases the temperature of the surroundings.
Note that while light and sound can sometimes be released, they are not the primary or typical forms of energy in most exothermic reactions.
Conclude that heat is the form of energy most commonly released during an exothermic chemical reaction.
