Question

Quizplus · Accepted Answer

Stretching a rubber band is a physical change because it changes the shape of the rubber band without altering its chemical properties. The other choices (A, B, D) involve chemical changes where the composition of the substance changes. Burning wood produces ash, rusting produces iron oxide, and exploding a firecracker produces new compounds.
