      Question

      If there is a circular hole in a metal plate, what

      happens to the radius of the hole when the plate is heated?
      A Increases Correct Answer Incorrect Answer
      B Decreases Correct Answer Incorrect Answer
      C Unchanged Correct Answer Incorrect Answer
      D Depends upon the metal Correct Answer Incorrect Answer

      Solution

      When a metal plate with a circular hole at its centre is heated, definitely along with the areal expansion of the plate the diameter of the circular hole also increases. Using the differential equations of coefficients of expansions, we find that the hole radius increases at the same linear rate as the metal.
