The statement that best describes a physical change is:
Changes can occur to certain physical properties of a substance, but the overall shape of the substance will remain the same.
In a physical change, the substance undergoes a change in its physical properties such as size, shape, state of matter (solid, liquid, gas), or density without changing its chemical composition. For example, when ice melts into water, the water retains the same chemical composition as the ice (H2O), but its physical state changes from solid to liquid. This is a physical change because only the physical properties of the substance are altered, not its chemical composition.
