physical- only its appearance has changed.
Physical. The properties of the metal do not change, and it can be undented.
It is a physical change because you are changing the shape of the metal.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
I think dhatt the answer is a physical change because if you just bent it then surley you can unbent it and still have a piece of metal.
The fact that sodium metal is soft enough to cut with a butter knife is a physical property. This property describes a characteristic of the substance itself without changing its chemical composition.
The sharpening of a metal knife blade is most often done in one or both of two ways:Removal of materialPlastic deformationThese both are physical changes. there might be a chemical sharpening but I do not know of it.
Yes, cutting a bar of sodium metal with a knife is a physical change, not a chemical change. The chemical composition of the sodium metal remains the same before and after cutting. The change is only in the physical state of the metal.
A metal burr is a small, thin edge of metal that is created when a piece of metal is machined. For example: when a chef's knife is sharpened, a thin piece of metal remains on the edge of the knife.
Oh, dude, cutting sodium metal with a knife is totally a physical change. It's like slicing a stick of butter, but way more explosive if you're not careful. So yeah, technically correct answer, but like, maybe don't try it at home unless you're looking for a science experiment gone wrong.
The blades can be sharpened, almost anything metal can be.

Physical change
It is a physical change because you are changing the shape of the metal.
Corrosion is a chemical change
Metal rusting (corrosion) is a chemical change.
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
yhe answer is the gallium is have nothing change thats why it is physical change
