Question

Help pls!!
What is the difference between physical change and chemical change?

Answer 1

The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question. In a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition

Hope this helped! :) Have a wonderful day/night!

Answer 2

Physical change does not make a new chemical/object. A chemical change does.

Chemical Change example: Combining liquid and liquid to create a new substance
