In this video we will learn about physical and chemical changes. We will go over several examples of each and then at the end of the video we will work on a few example problems where we determine if the process is a chemical or physical change.

  1. I was not interested in reading the book …cuz I am so lazy..so I taught that I can listen it in you tube video 👍👌🥰❤️
    Then …when I opened my book, I realized that it's not the correct chap which I read just now 🙁 😴😥

  2. summary:

    grinding – physical change
    folding – physical change
    ductility – physical change
    melting – physical change
    fermentation – chemical change
    combustion – chemical change
    oxidation – chemical change
    electrolysis – chemical change

    chemical changes: a change in a substance that involves a change in identity or chemical makeup of that substance. they are accompanied by a physical change.

    physical changes: changes in a substance that do NOT involve a change in the identity or chemical makeup of that substance.

  3. Summary:
    A physical change is when the substance changes. No new substances are made, and the change is often easily reversed. Changes of state are a physical change. No new substances are made, and it can be reversed easily.

    A chemical change is when the substance changes, and makes a new substance at the same time, for example: when wood burns, it creates burnt logs and smoke. This is also impossible to reverse. Unlike physical changes, a chemical change is not so easily reversed.
    You're welcome
