4. Physical changes are concerned with energy and states of matter. A
physical change does not produce a new substance. Changes in state
or phase (melting, freezing, vaporization, condensation, sublimation)
are physical changes. Examples of physical changes include crushing
a can, melting an ice cube, and breaking a bottle.
