Explanation:
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. A chemical change makes a substance that wasn't there before.
. Examples of Physical changes: 1. Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change.
A change can't be both physical and chemical, but physical and chemical changes can occur simultaneously. This is what's happening with the burning candle: the wax is melting, which is a physical change, and it's combusting, which is a chemical change. ... A chemical change is one in which a new substance is formed.
