Indicators of Chemical Changes
There are 4 indicators of chemical changes.
Heat & Light
Is the behavior of a substance when it undergoes a chemical change.
A physical change occurs when no new substance is produced. Physical changes deal with the physical properties of a substance.
Ex: change of state, slicing bread, malleable, ductile, breaking glass, and more.
Melting and Freezing Point
Are any properties that do not change the chemical state of matter.

A chemical change is a change that forms a new substance. For instance, if something is combustible, corrosive, rusting, tarnishing,or burning, then it will undergo a chemical change. Also, if you pay attention, light, heat, and sound play a factor in determining chemical changes.
Ex: Fireworks (combustion), wood burning, baking foods, and more.
Ex.: Density of Gold
Ex.: A Burning Page
