The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Change**: When ice (solid state of water) is heated, it melts and transforms into water (liquid state). This process involves a change in state from solid to liquid. 2. **Identifying the Type of Change**: To classify the change, we need to determine if it is a physical change or a chemical change. A physical change involves a change in state or appearance without altering the chemical composition of the substance. 3. **Reversibility of the Change**: Melting of ice is a reversible process. This means that if we cool the water back down, it will freeze and turn back into ice. The ability to reverse the process indicates that the change is physical. 4. **Chemical Composition**: During the melting process, the chemical composition of water does not change. Ice and water are both H2O, and their molecular structure remains the same throughout the melting process. 5. **Conclusion**: Since the melting of ice into water is a reversible change, does not alter the chemical composition, and only changes the physical state, we classify it as a physical change. **Final Answer**: Melting of ice into water is a physical change. ---
