Chemical Changes in Materials 

Reactivity refers to the ability of a material to react with another material. Substances or materials that make up things that undergo chemical change are called reactants. The new substances of materials produced at the end of the reaction are called products.

Chemical Changes in Materials

Materials can change in many ways. They can break, rip, tear, or fold, causing changes in shape and size. For example, a paper changes its shape and size when folded or shredded into smaller pieces. These are physical changes.

Materials can also burn, boll, rot, or decompose, causing changes such as changes in the color, temperature, and even the composition of materials. These are chemical changes which happen when a material undergoes a chemical reaction, which results in the formation of a new material.

When a chemical reaction occurs, the original materials are no longer present and may not be recovered physically.
