Physical properties of wool are the following; it is resistant to dirt and wear and tear, does not wrinkle easily, lightweight and versatile, smolders over flame instead of burning, hard wearing and absorbs moisture.
Melting the steel wool is a physical change.
Mostly good heat insulation properties.

When the steel wool burns, it is oxidized and thus this is a chemical 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.
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.
Wool is known for its excellent thermal properties as it insulates well, keeping the body warm in cold weather. It is also breathable, allowing moisture to escape, which helps regulate body temperature. Additionally, wool can retain its insulating properties even when wet.

One of the properties of wool is that it does not burn easily.When subjected to flames, it will smoulder instead.
Both are physical properties.
