Where is the warning? Right here! Steel wool is made of fine, thin strands of metal, which can conduct electricity. If steel wool comes into contact with both the positive and negative terminals of a battery at the same time, it can create a circuit and cause a short-circuit, which can lead to heat, sparks, fire, or explosion.The reason why steel wool is a good conductor of electricity is due to its metallic composition. Most metals, including steel, have a high density of free electrons in thei

Steel wool is made predominantly of iron and only a very small percentage of carbon. It is extremely thin with a great surface area, in fact if a difference of potential is applied (9V), it will be heated up, reaching a temperature of around 700°C. Therefore , the steel wool will burn with oxygen from the air producing iron oxide. That means the oxygen atoms are added to the iron atoms when the product iron oxide is formed, and this will cause an increase of mass. Remember mass in reactions is n
