    Boil water and the physical state changes from liquid to gas. Boil ice, and the water will go through the three most common states of matter. Alternately, break a pencil. the physical force will physically change the pencil, but not change its composition.

    What constitutes a physical change is a change in appearance and constitution. [i.e.; a rock falling down and breaking. This is a physical change because it alters the object's appearance and constitution. Another example is two substances (i.e.; milk and cocoa powder) being mixed together. This changes their appearance and constitution.]
