Chemical reactions that give off heat are called?

Endothermic
Exothermic
Hyperthermic
Isothermic

The correct answer is: Exothermic

Chemical reactions can be classified as either endothermic or exothermic based on the thermal energy exchanged during the reaction. Endothermic reactions require thermal energy to be absorbed from their surroundings, resulting in a decrease in temperature. Exothermic reactions, on the other hand, release thermal energy into their surroundings, resulting in an increase in temperature. Hyperthermic and isothermic are not correct answers because they are not related to the exchange of thermal energy during a chemical reaction. Hyperthermic refers to extreme heat, while isothermic refers to a constant temperature. Therefore, they do not accurately describe chemical reactions that give off heat.
