Answer:

The thermometer is made relatively small so that it is portable and cheap. The liquid is contained in a thin-walled glass bulb. The bulb is made relatively larger than its bore to contain more of the liquid, so as to improve sensitivity. The narrow bore of the capillary tube is uniform.

The bore of the thermometer tube will be uniform for the following reason -

  • The uniform bore of the capillary tube makes the thermometer more sensitive.
  • This is because a small expansion of the mercury in the bulb will cause a big change in the length of the mercury thread. The bulb is made of thin glass so that heat can be conducted quickly to the liquid.
  • The thermometer is made relatively small so that it is portable and cheap. The liquid is contained in a thin-walled glass bulb. The bulb is made relatively larger than its bore to contain more of the liquid, so as to improve sensitivity.
  • So, the narrow bore of the capillary tube is uniform.
