  • Q9
    The pot shown in the picture is made of two different metals. Why is the handle made of a different metal than the rest of the pot?
    Question Image
    The metal in the handle can absorb more energy without changing temperature as easily as the metal in the pot.
    The handle needed to be made out of a material that would not melt.
    It would have been too expensive to make the handle out of the same metal.
    The metal that the pot is made out of is too weak to make the handle.
