Explain why, melting of ice to form water is said to be a physical change.

Explanation

**Step-by-Step Solution:**

1. **Definition of Physical Change**: A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.

2. **Understanding Melting**: When ice is heated, it undergoes a process called melting. During this process, the solid ice (which is in a solid state) absorbs heat and changes its state to liquid water.

3. **No New Substance Formed**: In the melting of ice, the chemical composition of the substance remains the same. Ice (solid water) and water (liquid water) are both forms of H2O. Therefore, no new substance is formed during this change.
