What makes ice a chemical change?

Answer 1

Water changing into ice does not have a chemical reason, as it is not a chemical reaction but a physical change. It changes its state of matter once reaching the freezing point of 0 degrees Celsius, and freezes.

Answer 2

Ice undergoes a chemical change when it melts and changes state from a solid to a liquid. Despite the physical appearance remaining similar, the internal structure of the ice molecules is altered as they gain energy to break free from their fixed positions. This transformation does not involve a change in the chemical composition of the water molecules themselves.

Answer 3

Water turns into ice, but the water does not undergo any chemical changing. Therefore ice is a physical change.
