Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
