Is rusting steel wool a physical or chemical change?
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.
Is wool forming on sheep a chemical change or a physical change?
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.
How can you say that the wool being knitted is a physical change?
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.
Does steel wool have iron in it?
Yes, steel wool is made of steel, which is primarily composed of iron. Steel wool is a bundle of very fine and flexible sharp-edged steel filaments, making it abrasive and effective for cleaning and polishing tasks.
What happens when you put steel wool in water?
Steel wool will quickly start to rust when placed in water due to its iron content. The water exposes the iron to oxygen in the air, leading to oxidation which causes the steel wool to rust and eventually deteriorate.
What is a physical change of steel wool?
Melting the steel wool is a physical change.

Why is it physical change if the steel wool turned the black pot shiny silver?
Physical change: the steel wool only changes the black pot's shape and in doing so reveals another color in the pot or the color of the substance that the pot is made from; it would still be the same thing but there would be all the parts of the pot, just it would be in different pieces.
What is the chemical name of steel wool?
Steel wool is made from an iron alloy, not a chemical compound with a formula.
How is weathering of steel wool like the weathering of a rock?
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.

What chemical change produces light and heat?
steel wool burns in oxegen and produces heat and light
What Chemical change that produces light and heat?
steel wool burns in oxegen and produces heat and light
What is the chemical formula of steel wool?
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.
What type of bond holds steel wool together?
Steel wool is typically held together by metallic bonds, which are formed between the atoms within the metal. These bonds involve the sharing of electrons among the metal atoms, creating a strong bond that gives steel wool its structural integrity.
Is spinning wool into yarn a physical change?
yes because only the appearance changed and it is still wool.
