Whether a chemical reaction is endothermic or exothermic relies on how much energy is added (endo) in bond breaking and how much energy is given off (exo) in bond making.
Endothermic change---> If more energy is added than given off
Exothermic Change---> If more energy is given off than is added.
Example of exothermic change: formation of chemical bonds
Example of endothermic change: melting of ice cubes
Potential energy: energy associated with position
Kinetic energy:: Energy related to motion
