Its a physical change because the substance does not form and etc.
Frost is a physical change, the condensation and freezing of water vapor.
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.
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.
No, ice does not undergo a chemical change when it freezes. Freezing is a physical change that causes water molecules to slow down and come closer together, forming a solid structure with the same chemical composition as liquid water.
A scab forming over a wound is a physical change. It occurs due to the process of coagulation, where blood cells and proteins solidify to form a protective layer over the wound.

No it is not. The chemical composition is H2O before and after freezing.
No, it is a physical change, like boiling, melting and freezing
physical changes, like freezing, boiling, cutting, breaking, bending
chemical
The formation of an icicle on the roof is a physical process. It occurs when water freezes due to the temperature being below freezing point, leading to the solidification of the liquid water into ice.

It is a physical change: water changes from gas to solid.
