Can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.
Chemical changes involve chemical reactions and the creation of new products. Typically, a chemical change is irreversible.

combustion (burning) of wood

Of matter describes its "potential" to undergo some chemical change or reaction by virtue of its composition. What elements, electrons, and bonding are present to give the potential for chemical change.
