    Rate this question:

  • 2. 

    The element iron

    • A.

      Is a red/brown color.

    • B.

      Does not rust.

    • C.

      Rusts very easily.

    • D.

      Is not magnetic.

    Correct Answer
    C. Rusts very easily.
    Explanation
    Iron is known for its tendency to rust easily when exposed to moisture and oxygen. Rust is a chemical reaction that occurs when iron reacts with oxygen in the presence of water, forming iron oxide. This process is accelerated in the presence of salt or acidic conditions. Therefore, the statement "rusts very easily" is the correct answer.

    Rate this question:

  • 3. 

    Iron is solid at room temperature.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Iron is a solid at room temperature because it has a high melting point of 1538 degrees Celsius and a boiling point of 2861 degrees Celsius. This means that at typical room temperatures, which range from around 20-25 degrees Celsius, iron remains in its solid state. It has a crystalline structure and is known for its strength and durability, making it a commonly used metal in construction, manufacturing, and various other industries.

      Nickel

    • C.

      Oil

    • D.

      Galvenite

    Correct Answer
    A. Zinc
    Explanation
    Adding an exterior of zinc helps reduce rusting.

    Rate this question:

  • 5. 

    The primary use of iron is to manufacture.

    • A.

      Beverage cans

    • B.

      Magnets

    • C.

      Roofs

    • D.

      Steel

    Correct Answer
    D. Steel
    Explanation
    Iron is primarily used to manufacture steel. Steel is an alloy of iron that is widely used in construction, manufacturing, and various industries due to its strength and durability. It is used to make structures like buildings, bridges, and vehicles, as well as a wide range of products such as appliances, machinery, and tools. Iron alone is not commonly used in the manufacturing of beverage cans, magnets, or roofs, but it is a key component in the production of steel, which is essential for these applications.

    The United States is the world's largest producer of iron ore.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The United States is the world’s 8th largest producer of iron ore. The top 7 producers are China, Australia, Brazil, India, Russia, Ukraine, and South Africa.

    Rate this question:

  • 7. 

    Iron melts at a temperature of

    • A.

      2,800 °F (1538 °C)

    • B.

      3020 °F (1660 °C)

    • C.

      387°F (197°C)

    • D.

      212°F (100 °C)

    Correct Answer
    A. 2,800 °F (1538 °C)
    Explanation
    Iron melts at a temperature of 2,800 °F (1538 °C) because this is the temperature at which the solid iron changes into a liquid state. At temperatures below 2,800 °F, iron remains in its solid form, but once it reaches this temperature, the heat causes the iron atoms to vibrate more rapidly, breaking the bonds that hold them together in a solid lattice. This allows the iron to flow and take on the properties of a liquid.

    Rate this question:

  • 8. 

    Iron can be found in

    • A.

      Distilled water

    • B.

      Meteorites

    • C.

      Bronze statues

    • D.

      Brass materials

    Correct Answer
    B. Meteorites
    Explanation
    Iron can be found in meteorites. Meteorites are solid objects that originate in outer space and survive their passage through the Earth's atmosphere and impact the Earth's surface. They often contain a variety of minerals, including iron. Iron is a common element found in the Earth's crust, and it is also present in various other materials such as distilled water, bronze statues, and brass materials, but meteorites are specifically known for their iron content.

    Iron is the most abundant metal in the earth’s crust.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Aluminum is the most abundant metal in the earth’s crust. Iron is the second most abundant, and the core of the earth is solid iron.

    This process was patented in 1855 and was the first patented process for mass-producing steel from molten pig iron, and many sites this event as the catalyst for the industrial revolution.

    • A.

      Carnegie Process

    • B.

      Bessemer Process

    • C.

      Scunthorpe Process

    • D.

      Frick Process

    Correct Answer
    B. Bessemer Process
    Explanation
    The Bessemer process, credited to Englishman Henry Bessemer, revolutionized steel manufacturing by decreasing its cost by 80%.

  • 11. 

    Which is a common ore that iron is extracted from?

    • A.

      Gypsum

    • B.

      Hematite

    • C.

      Calcite

    • D.

      Forsterite

    Correct Answer
    B. Hematite
    Explanation
    Hematite is a common ore that iron is extracted from. It is a mineral form of iron oxide and is typically black or reddish-brown in color. Hematite is widely distributed and found in abundance in various parts of the world. It is an important source of iron due to its high iron content and is commonly used in the production of iron and steel.

    Rate this question:

  • 12. 

    What the main element from iron ore has to be removed to get iron? 

    • A.

      Hydrogen

    • B.

      Sodium

    • C.

      Carbon

    • D.

      Oxygen

    Correct Answer
    D. Oxygen
    Explanation
    Iron ore is a compound that contains iron and oxygen. In order to obtain pure iron, the oxygen needs to be removed from the iron ore. This is typically done through a process called smelting, where the iron ore is heated at high temperatures in the presence of a reducing agent, such as carbon. The carbon reacts with the oxygen in the iron ore, forming carbon dioxide and leaving behind pure iron. Therefore, the correct answer is oxygen.
