Explanation:

Physical Change:
- Melting of ice is a physical change.
- In a physical change, the substance undergoes a change in its physical state without changing its chemical composition.
- When ice melts, it changes from a solid state to a liquid state without any change in its chemical composition.

Chemical Change:
- A chemical change involves a change in the chemical composition of the substance.
- For example, when wood burns, it undergoes a chemical change as the composition of wood changes due to the formation of new substances like ash and gases.

Melting of Ice:
- When ice melts, it only undergoes a physical change as it changes from a solid state to a liquid state without any change in its chemical composition.
- The molecules in ice gain enough energy to overcome the forces holding them in a solid state, leading to the melting of ice into water.
- The chemical composition of water remains the same before and after the melting process.
Therefore, melting of ice is a physical change and not a chemical change.
