Exploring the Combustion of Steel Wool

What is the main purpose of the burning steel wool experiment?

• To observe the combustion of steel wool

• To create a new type of steel

• To test the strength of steel wool

• To measure the electrical resistance of steel wool

Which type of steel wool is recommended for this experiment?

• Superfine or extra-fine

• Medium

• Coarse

• Ultra-coarse

Why is it important to perform this experiment outdoors?

• To avoid indoor pollution

• To ensure proper ventilation

• To get better lighting

• To prevent the spread of fire

What should you do if the steel wool catches fire uncontrollably?

• Cover it with a cloth

• Pour water on it

• Blow on it

• Use a fire extinguisher

What happens when you touch a 9-volt battery to the steel wool?

• It glows and sparks

• It melts

• It changes color

• It becomes magnetic

Why does the steel wool weigh more after the experiment?

• It loses electrons

• It expands

• It gains mass from oxygen atoms

• It absorbs moisture

What is an alloy?

• A form of non-metal

• A mixture of two or more metallic elements

• A type of chemical compound

• A single pure metal

What is the main component of steel used in this experiment?

• Aluminum

• Nickel

• Copper

• Iron

What is the role of electrical resistance in this experiment?

• It makes the steel wool magnetic

• It changes the color of steel wool

• It cools down the steel wool

• It causes the steel wool to heat up
