Changes
This Video has perfect examples of Physical/ Chemical changes. A physical change is when something changes shape but is the same substance. A chemical change is when the substance changes COMPLETELY or, even makes a new substance.
PROPERTIES:
A property, like I said before, is a characteristic. It describes the substance. For example; if you had a blue whale, (not that you have one... I hope so...) it would be blue. That is an example of a physical property. Chemical is way different. For example FE, or iron, is metal. It will rust. That is a chemical property. Paper will burn. Chemical.
