Physical changes are often referred to as chemical reactions but as you will see in this article they sometimes are not…
You can always tell if a reaction is chemical or physical as they have some telltale features such as light, smell, sound, heat (decrease & increase) and gasses being produced.
Physical changes are also called State Changes (Solid, Liquid & Gas) and they may sometimes change colour temporarily, while being heated / cooled.
Some examples of physical changes include freezing water to get H2O[S] or boiling water to get vapor H2O[G].
