Definition
Exothermic Reaction
A chemical reaction that releases energy, usually in the form of heat.
Endothermic Reaction
A chemical reaction in which energy is absorbed
What's the main difference between an exothermic and endothermic reaction?
An exothermic reaction releases energy and feels warm while an endothermic reaction absorbs energy and feels cool.
Sara mixed water and calcium chloride. The reaction made the water turn cloudy. The temperature of the reaction went from 23 degrees C to 52 degrees C. Is the reaction exothermic or endothermic?
Exothermic
Samuel mixed baking soda with hydrochloric acid. The reaction bubbled and the temperature went from 52 degrees C to 22 degrees C. Is the reaction exothermic or endothermic?
Endothermic
