True or false: Chemical and physical changes alter matter?

False

Explanation:

Chemical changes do change the composition of the substance. However, physical changes do not; physical changes simply alter the physical form of the substance.

For example, a melting ice cube is undergoing a physical change, but its overall composition of H2O isn't changing. It's just changing from a solid form to a liquid form.
