⠀

Physical Change :-

• This is a change where the molecules rearrange themselves but no changes in internal composition happen
• These changes are reversible in nature
• It impacts the physical properties like shape, size, colour and more
• Cutting of wood, freezing water, melting ice cubes, crushing a tomato are physical changes

⠀

Chemical Change :-

• Chemical change transforms the substance into a new one and gives it a different chemical composition
• It is an irreversible change
• This impacts the chemical properties as well as the physical properties
• Burning of wood, digesting of food, baking of cake, rusting of iron are examples
