Detailed explanation-1: -Ice is solid and the water in the pool is liquid. So, they are in different states of matter. False.
Detailed explanation-2: -The chemical composition of water in all the three states (ice, water and steam) is same, i.e., H2O.
Detailed explanation-3: -The correct answer is Freezing of water. Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. Freezing of water is not a chemical change as ice when melt changes back to water showing the physical change.
Detailed explanation-4: -As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. It possesses a regular crystalline structure based on the molecule of water, which consists of a single oxygen atom covalently bonded to two hydrogen atoms, or H–O–H.
Detailed explanation-5: -Therefore, ice, water and steam have different physical states but are chemically identical.
