A forest fire being put out is a physical change.
A physical change refers to a change in the physical properties of a substance without altering its chemical composition. In the case of a forest fire, extinguishing it involves cooling the area, removing the heat source, or cutting off the oxygen supply. These actions cause the fire to be extinguished, but they do not change the chemical composition of the burning materials.
