Physical changes occur when objects undergo a change that does
not change their chemical nature. A physical change involves a change
in physical properties. Physical properties can be observed without changing
the type of matter. Examples of physical properties include: texture,
shape, size, color, odor, volume, mass, weight, and density.
| An exmple of a physical change occurs when making
a baseball bat. Wood is carefully crafted into a shape which will
allow a batter to best apply force on the ball. Even though the
wood has changed shape and therefore physical properties, the
chemical nature of the wood has not been altered. The bat and
the original piece of wood are still the same chemical substance.
