Is Freezing Water A Chemical Change. The chemical change also usually involves heat, burning, or other interaction with energy. Why is water freezing not a chemical change?
Why is water freezing not a chemical change? Freezing water is not a chemical change. When liquid water (h2o) freezes into a solid state (ice), it appears changed;
Then the change in density of the altered liquid reverses and starts. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
Water turning from liquid to solid form is. In a chemical change, a new substance is formed. Freezing water is a physical change.
This is a physical change because the ice still has the same molecular components as when it was in a liquid state. As most of the food have 80 % or more water content which gets converted into ice and ice being a solid form of water though chemically same (h2o), it gets hardened. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes.
In a chemical change, a new substance is formed. The liquid achieves its maximum density, at which point the water starts to form ice crystals. 11.19% hydrogen and 88.81% oxygen by mass.
On the other hand, chemical changes are a bit different. A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. When liquid water (h2o) freezes into a solid state (ice), it appears changed;
