Physical and Chemical Change
There are many questions about the difference of physical and chemical change.
As stated above, there are many questions about physical and chemical change. In all honesty, the names answer your questions. A chemical change is when change occurs whenever matter changes into an entirely different substance with different chemical properties. Physical change is a change in one or more physical properties of matter without any change in chemical properties. Basically its chemical substance doesn't change but it's physical change does. So, the difference here is that chemical change is when the chemical substance changes, and physical change is when the physical state of the substance changes but the chemical substance doesn't.
