Is freezing of water chemical change
WebOct 8, 2024 · The freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory, the two temperatures would be the same, but ... WebMar 26, 2024 · Water freezing into ice is a physical change because the hydrogen and oxygen molecules that make up the water stay the same, despite the change in state from liquid to solid. A physical change is simply a change in the material’s physical properties, such as shape or phase.
