Question

Mercury boils at 356 degrees celsius, however, mercury thermometers are made such that they can measure temperatures up to 500 degrees celsius. This is done by?

Answer 1

• The boiling point of mercury is $356°C$.
• Mercury thermometers can measure a temperature up to ${500}^{\circ }C$, as these thermometers are mixed with nitrogen gas at high pressure.
• This causes an increment in the boiling point of mercury.
• And, now it can measure temperature beyond $356°C$ and up to ${500}^{\circ }C$.
