1210 - What form does energy change take in a chemical reaction?

In a chemical reaction, energy can change in two main forms:

  1. Heat Energy: It can be released or absorbed, making the reaction feel hotter or cooler. Examples include burning wood or a firecracker explosion.

  2. Light Energy: It can be released or used up, making the reaction give off light or not. Examples include fireworks explosions or a glow stick.

This process is known as 'Energy Transformation', where one type of energy changes to another type of energy during a chemical reaction.
