physical change and chemical change

Asked by KennethXhianDee824

Answer (1)

Physical change is a change that affects only the physical properties of a substance, like its shape, size, or state, without changing its chemical composition. It is usually reversible. Examples include melting ice, tearing paper, or dissolving sugar in water.Chemical change, on the other hand, involves a change in the chemical composition where new substances with different properties are formed. This change is usually irreversible and is often accompanied by energy changes like heat, light, or color change. Examples include burning wood, rusting iron, or cooking food.
