What is the difference between a physical change and a chemical change?
A physical change can be reversed, whereas a chemical change cannot.
A physical change only affects the appearance of a substance, whereas a chemical change affects its properties.
A physical change involves a change in temperature, whereas a chemical change does not.
The difference between a physical change and a chemical change is that a physical change does not involve a change in chemical composition, whereas a chemical change does.
