What is a Physical Change? In a physical change, the internal make-up of the object (molecules) stays the same, even after the change â only its form changes. The resulting element can be reversed into the object before. Changes that can be reversed are called a Reversible Change. In a physical change, the state, shape or size of the object is changed. Pressure, temperature or motion can bring about a physical change. Change in state: Put some water into a plastic cup and place it in the freezer. After sometime the water changes into ice, right? The water moved from a liquid state to a solid state.
