The answer is True. Mercury has a freezing point at -37∘C
. For every material, freezing point makes the liquid as solid. For the thermometer applications, liquids have to be freely-flowing. Otherwise, it will show the wrong measurements.
Complete step by step answer: Even though mercury thermometers have a wide range of temperature measurement (−37 to 356∘C)
, it can’t be used for the lower temperatures. As we know, the mercury will solidify itself at −38.83∘C
. For the extension of temperature range, inert gas like nitrogen will add into the mercury. So, when the mercury becomes solid at lower temperatures, the nitrogen gas will get trapped. When we reuse this thermometer for the high-temperature measurement, it will behave like an unstable thermometer. So, we have to repair this thermometer for further use if we have used a mercury thermometer at lower temperatures. It is very difficult to use mercury thermometers at a lower temperature since the mercury solidifies at lower temperatures.
Hope this is going to help you.
