Physical change refers to a change in the physical characteristics or properties of a substance without altering its chemical composition. For example, changing the shape, size, or state of matter, such as melting ice into water or breaking a piece of glass, are physical changes. In these changes, the substance remains the same at a molecular level.
Chemical change, on the other hand, involves a transformation at the molecular level where the chemical composition of a substance is altered, forming new substances with different properties. It typically involves the breaking and forming of chemical bonds. Examples of chemical changes include the rusting of iron, the burning of wood or paper, or the digestion of food in our bodies. In these changes, the original substances are converted into new substances.
