When a piece of steel wool is burned it gains mass. Which explanation is consistent with the law of conservation of mass?
When steel wool is burned, it is merely an acceleration of the natural oxidation process that wool is constantly undergoing. The wool is not actually burning, it is actually rusting at a very fast pace, leaving behind iron oxide in its place. The additional mass comes from the addition of the oxygen atom bonding to the already present iron atoms.
Why does iron wool burn better than an iron nail?
Since filaments of iron wool are much thinner than an iron nail, they therefore have a much higher ratio of surface area to volume, and burning takes place at the surface, so the more surface, the more easily it burns.

Why wool burns with the smell of burning hairs?
Wool is made of protein fibers that are similar to the composition of human hair. When wool burns, the sulfur-containing amino acids in the protein break down to release a distinct smell similar to burning hair. This is due to the keratin structure in wool, which is also present in hair and nails.
When we burn wool why do we get the smell of hair burning?

Why does silk or wool are burnt they smell like burning hair?
Silk and wool are protein-based fibers, just like hair. When burned, they release a similar odor due to the presence of sulfur-containing amino acids in their molecular structure. This shared chemical composition is what causes the burning smell to resemble that of burning hair.
How do you prove a ball of wool is real wool and not man made?
The simplest, but not definitive, test is to burn a small amount. Wool will not ignite readily, but when it does burn smells like burning hair and what little ash it creates is "soft". Man-made fibres will generally ignite quickly, have an acrid smell and leave a hard or beaded ash.

Why wool on burning gives smell to burning hair?
Both wool and hair are made of keratin, a protein that contains sulfur. When wool or hair burns, the sulfur is released as a gas called sulfur dioxide, which has a distinct smell akin to burning hair or feathers. This odor is a result of the chemical composition of the materials as they break down under heat.
