A circular hole in an aluminum plate is 2.725 cm in diameter at 0.000 degrees celsius. What is its diameter when the temperature of the plate is raised to 100.0 degrees celsius?

  • Physics -

    the hole gets bigger.

    deltaDiameter=OrigDiameter*coeffexpan*deltaTemp

    so the new diamter=origDiameter+deltaDiameter.
