A physical change is a change where no new substance is formed.

Physical changes affect the form of a substance, but not what it's made up of.

Some physical changes are reversible and their mass does not change.

An example is a change in shape. You could melt an ice cube. The shape has changed but it is still made of the same substance. You can also re-freeze it.

Other examples of a physical changes are tearing a piece of paper, chopping up some wood are also an examples of a physical change.

Many physical changes also involve the rearrangement of atoms most noticeably in the formation of crystals.

Unlike physical changes many chemical changes are irreversible.
