The spoiling of a peach is an example of a chemical change. When a peach begins to spoil, it undergoes various processes that alter its chemical composition. These changes are usually caused by the action of bacteria, yeast, and mold that break down the organic matter in the fruit.
During this process, the sugars in the peach may ferment, producing alcohol and other byproducts, and the fruit may turn soft and discolored. These are signs of decay and indicate that the chemical structure of the peach is changing. Unlike physical changes, which do not alter the fundamental properties of a substance (like cutting a peach in half), chemical changes result in the formation of new substances that have different properties. Therefore, the spoiling of a peach is indeed a chemical change.
