Difference between physical change and chemical change.
Physical Change vs Chemical Change
Physical change is a temporary process that can be reversed or brought back to its original state. So, it is a reversible process. No new products or substances are formed in this change. It brings change in only the physical properties of matter like shape, size, etc. It does not affect the change of chemical bonds of atoms or molecules, and due to this, no energy is produced during this change. In this composition of matter is not changed.
While a Chemical change is a permanent change that cannot be reversed. So, it is an irreversible process. In a chemical change, new substances and products are always formed. In contrast to physical change, and as the name clarifies, it has a direct effect on the chemical bonds of molecules or atoms, and due to this, energy is produced during this change. In this composition of matter is changed.
Let us understand completely with the help of an example –
* Melting of ice is an excellent example to explain physical change.
* Burning of wood is an excellent example of chemical change.
