In most chemical reactions, energy is transferred into or out of the system. Energy in the form of heat and light are transferred out of the reaction of a candle burning. Chemical Reactions, Grades 9-12 Chemical reactions may release or consume energy. Burning paraffin releases heat and emits light. An example of this phenomenon is the movement of heat from warmer to cooler objects.
Heat disperses into the environment as a candle is burned.
