Answer:
Physical Change
Properties such as shape, size, state of the substance and its colour are known as physical properties. Physical properties are affected by the physical change.
Chemical Change
A change in which one or more new substances are formed is known as chemical change
Rusting of Iron
When substances made of iron are exposed to oxygen and moisture (water), rusting takes place. Rusting removes a layer of material from the surface and makes the substance weak. Rusting is a chemical change
Crystallization
A physical process of obtaining large crystals of a pure substance from its solution is known as crystallization. Crystallization is a physical change.
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
