Hey,
Ur answer is here,
Key Differences Between Physical Change and Chemical Change
1.A change in which the molecules are rearranged, but their internal composition remains same is called Physical Change. A process in which the substance transforms into a new substance, having a different chemical composition, it is known as Chemical Change.
2.Some common examples of physical change freezing/melting/boiling of water. the examples of chemical change are combustion, metabolism, etc.
3.Physical change is a temporary; they are easily reversible. As against this, the chemical change is permanent in nature, i.e. they cannot be reversed, even by reversing conditions.
4.In the physical change, only the form of the substance is changed, but no new product is formed. On the other hand, when there is a chemical reaction, a completely different product is formed, whose properties are completely different from that of the reacting substances.
5.In a physical change, the original matter can be recovered, by simple physical methods. As opposed, in chemical change the original matter no longer exist, and so it cannot be recovered.
6.In the physical change, no or very little amount of energy is absorbed or given out as heat, light or sound energy. Unlike chemical change, wherein enormous energy is absorbed or given out as heat, light or sound energy
Hope it helps you ☺️
