Question Are the changes of water to ice and water to steam, physical or chemical? Explain.
Both, the change of water to ice and water to steam are physical changes. In both processes, the chemical composition of water remains the same; only its state changes from liquid to solid (ice) or from liquid to gas (steam). No new substance is formed which is a characteristic of physical changes.
