PD3 - MRMS MP2: 2025: Exothermic/Endothermic Flashcard

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat, causing the temperature of the surroundings to increase.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, resulting in a decrease in temperature.

Front
