Questions and Answers

What is the primary advantage of adding carbon to iron to create steel?

  • It increases the metal's malleability.
  • It enhances the metal's thermal conductivity.
  • It strengthens the metal by preventing iron atoms from sliding. (correct)
  • It makes the metal lighter.

    • Which process involves melting metal and pouring it into a mold?

  • Casting (correct)
  • Smelting
  • Forging
  • Alloying

    • What occurs during the smelting process?

  • Iron metal is transformed back into iron ore.
  • Molded metals are hardened under heat.
  • Iron oxide reacts with carbon to produce iron and carbon dioxide. (correct)
  • Metals are combined to form an alloy.

    Study Notes

    Metal Concepts

    • Forging (Smida): Shaping metal by hammering
    • Casting (Gjuta): Shaping metal by melting and pouring into a mold
    • Alloy (Legering): A mixture of metals or a metal with non-metals
    • Steel (Stål): An alloy of iron and carbon; stronger and harder than pure iron due to carbon atoms preventing iron atoms from sliding past each other.
    • Bronze (Brons): An alloy of copper and tin; one of the earliest alloys discovered

    Metal Alloying Details

    • Alloys: Combinations of metals or a metal with small amounts of non-metals.
    • Steel: An alloy of iron and carbon. Carbon atoms prevent iron atoms from sliding past each other, making steel stronger and harder
    • Bronze: An alloy of copper and tin. One of the first alloys used by humans.

    Metal Manufacturing

    • Blast Furnace (Masugn): Industrial facility that converts iron ore into iron metal through a chemical reaction of iron oxide and carbon.

    Corrosion

    • Corrosion: Chemical reaction between a metal and other substances (often oxygen) forming ionic compounds.
