When the steel wool burns, it is oxidized and thus this is a chemical change.
Steel wool is made from an iron alloy, not a chemical compound with a formula.
Rusting of steel wool is a chemical change because it involves a reaction between iron in the steel wool and oxygen in the air to form iron oxide (rust). This new substance has different properties than the original steel wool.
Let's call it a biological change. It has elements of both physical and chemical, but wool doesn't "form" on a sheep like, say, mold on a loaf of bread; wool is sheep hair and it grows out of hair follicles all over the animal.
Wool is a protein fibre. Proteins are chains of amino acids. In fibres their beta structure keeps the chains from coiling up.
it has chemical that is on the wool that help the wound heal.
There's none. Wool came from sheep! Wool belongs to a group of proteins (chemicals!) known as keratins. Unlike cotton and the majority of synthetic fibres, wool does not have a homogenous structure. Wool fibres have highly complex physical and chemical compositions.
Wool is a natural fiber obtained from animals such as sheep, goats, and alpacas. It is not a synthetic fiber, which is man-made from chemical compounds.
The process of knitting wool involves only a rearrangement of its fibers to create a new structure, without altering the chemical composition of the wool itself. Since no new substances are formed and the wool can be returned to its original state by unraveling the knit, it is considered a physical change.
steel wool burns in oxegen and produces heat and light
The chemical formula of steel wool is Fe, which represents the element iron. Steel wool is composed mainly of iron, with small amounts of other elements depending on the specific type or grade of steel.
Both steel wool and rocks undergo physical and chemical weathering processes when exposed to the elements. Steel wool can rust when exposed to moisture, similar to how rocks can break down due to freezing and thawing cycles or chemical reactions with water. Both processes result in the breakdown of the material over time.
