Question

question 4 (1 point) is this a chemical or a physical change? hammering a nail into a piece of wood a chemical change b physical change

Explanation:

Physical changes do not change the chemical composition of a substance. Hammering a nail into wood only changes the shape and position of the nail and wood, without altering their chemical makeup. Chemical changes involve the formation of new substances with different chemical properties. Since no new substances are formed here, it is a physical change.
