You can tell a chemical and a physical change apart because a physical change is any change in size, shape, form, or state where identity of the matter stays the same.Example of a physical: If you cut a watermelon into chunks, the watermelon has changed size and shape.If you put one of the chunks into your mouth and bite it you have changed the size and shape again.Chemical change occurs when one type of matter changes with different properties chemical change goes around you everyday.Signs of a chemical change are the formation of a gas.yes because i wrote it!
