Question

1. how is ice melting different from burning something?

Explanation:

Melting ice is a physical change. The chemical composition of water remains \(H_2O\) whether it is in solid (ice) or liquid (water) state. Burning something is a chemical change. New substances are formed. For example, when wood burns, carbon dioxide, water vapor, and ash (containing various minerals) are produced. The chemical composition of the original substance (wood) is altered.

Answer:

Melting ice is a physical change (no new substances formed, same chemical composition \(H_2O\)), while burning something is a chemical change (new substances formed, chemical composition altered).
