Thermal expansion of solids, liquids and gases — practice question

A liquid-in-glass thermometer is made up of a bulb that contains a liquid, and this liquid expands into a narrow capillary tube. In the thermometer, the liquid is swapped for another liquid of the same volume that undergoes a larger expansion for the same increase in temperature. The capillary tube stays the same length. How does the new thermometer compare with the old thermometer?

  • AIt has greater sensitivity and a greater range.
  • BIt has greater sensitivity but a smaller range.
  • CIt has the same sensitivity and the same range.
  • DIt has the same sensitivity but a greater range.
