Mercury boils at 367∘C367^{\circ} \mathrm{C}. However, mercury thermometers are made such that they can measure temperature upto 500∘C500^{\circ} \mathrm{C}. This is done by

Options

  1. Amaintaining vacuum aboves mercury column in the stem of the thermometer.
  2. Bfilling nitrogen gas at high pressure above the mercury column.
  3. Cfilling oxygen gas at high pressure above the mercury column.
  4. Dfilling nitrogen gas at low pressure above the mercury column.

Correct answer

B. filling nitrogen gas at high pressure above the mercury column.

Step-by-step solution

If we fill nitrogen gas at high pressure above mercury level, the boiling point of mercury is increased which can extend to the range upto 500∘(C)500^{\circ}(C).
