Are icicles forming on the edge of the roof of physical or chemical change?
No it is not. The chemical composition is H2O before and after freezing.
Is freezing h2o physical or chemical property?
physical, ice is still H2O
How is freezing a physical change?
Freezing of ice is a physical change as ice can be turned back to water by heating. It has retained its chemical properties and underwent only a physical change (changing shape from water to ice). Hence it is a physical change.
Is melting a physical change to metal?
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
Melting ice. Chemical or physical change?
Physical. H2O is still H2O.
Classify as chemical and physical change-freezing of water?
Freezing of water is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of water. The molecules in water rearrange to form a crystalline structure in the solid state but remain as H2O molecules.
Is drying water chemical change or physical change?
Physical, it is still H2O
Is the chemical formula H2o physical or chemical change?
The chemical formula H2O represents water. It is a chemical formula that describes the composition of a substance, in this case, water. Therefore, it is related to a chemical change rather than a physical change.
Why is the electrolysis water classified as a chemical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
Is an ice cube and water a physical or chemical change?
A physical change because the substance does not change. It is still H2O, but in a different form.
Is ice cubes forming in the freezer a chemical reaction?
No, freezing water is a physical change, not a chemical one since no chemical reaction takes place. The water molecule (H2O) remains the same even though the physical state changes from a liquid to a solid.
Is water freezing to form ice a chemical or physical change?
well ! actually it is a very simple phenomenon.....because of the icy cold water, the air around it gets condensed when it comes close enough. consequently, the condensation causes the water vapors in the air to change into droplets that then appear on the surface of the container of that icy cold water...
