The steel wool turns blue after burned. The mass also increases.
When steel wool is burned, the iron in the steel reacts with oxygen in the air to form iron oxide (rust) and heat. The heat generated accelerates the reaction, causing the steel wool to rapidly glow and disintegrate into small pieces. As a result, you will see sparks and potentially some flames as the steel wool burns.
Scrub it with a wire brush and steel wool.
Yes, steel wool can rust. Steel is a ferrous material, meaning it is mostly iron. Rust is iron oxide. Thus, if you keep steel wool wet, it will certainly rust. Adding an oxidizer will increase the rate of this process as well.
Electricity is energy. Energy can be different things. We have movement as an energy, kinetic energy that is. Then there is, amongst others heat, as an energy. Electricity must be in a circuit to work. When putting the 9volt battery in the steel wool you make a circuit. Then the electricity will flow through the steel wool. When the electricity is not being used by anything (no light bulbs or anything), it is being converted to heat energy. Steel wool burns easily, so the heat will easily ignite the steel wool.
burns faster in pure oxygen as the percentage of oxygen is less in air
steel wool is steel made from wool, so it would be neither
the wool does not rust
Steel wool is a mixture.
Steel wool is a Mixture-Mechanical
Steel wool
Depends on whether you leave the steel wool in the Pepsi. If you take it out, the water in the Pepsi will cause the steel wool to rust away. If you leave it in, the phosphoric acid will slowly dissolve the steel wool.
Melting the steel wool is a physical change.
