No it is not. The chemical composition is H2O before and after freezing.
It is a physical change: water changes from gas to solid.
because the chemical composition of the nail is changed, forming a new substance (the rust)
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
water forming water vapor is physical change

An 'iceberg' is no kind of change, but the melting and forming is a physical change.
Forming a bar of gold into wire is considered a physical change. This is because the gold's chemical composition remains the same during the process, only its physical shape is altered.
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
No, it is a physical change, like boiling, melting and freezing
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
Forming a bar of gold into wire is a physical change. This is because the chemical composition of the gold remains the same, and only its physical shape and properties have been altered.
