Why mercury is used as a thermometric fluid ?
Sol:
There are many reasons for using mercury as a thermometric liquid, here are listed a few:
- Mercury has high melting and boiling points making it a liquid over a broad range of temperature.
- Since it is a metal, it has a stable coefficient of expansion hence it expands uniformly and noticeably for a slight change of temperature.
- Mercury is a non sticky viscous metal and hence it makes a clear meniscus, helpful in readings.
- Mercury will not expand when it solidifies hence it doesn’t break the glass tube of the thermometer.
