Q. Reasons for using mercury in thermometers.
Top Answer
Solution:
Reasons for using mercury in thermometers.
- Mercury is a good conductor of heat.
- Mercury does not stick to the glass capillary tube in the thermometer.
- Its freezing point is -39°C and boiling point is 357°C. Hence, the range of a mercury thermometer is quite large.
- Mercury remains liquid over a wide range of temperatures, from very cold to very hot.
- It can measure very high temperatures without evaporating.
- It is easily obtained in pure form.
- Mercury is an opaque and shining liquid. Hence, it can be seen as a fine thread in the capillary tube.
