Mercury is used as a thermometric liquid. Give reason.

We know that mercury is only the metal that exists in the state of liquid with a freezing point - 39°C and boiling point 357°C. The range of its FP and BP is suitable for measuring normal temp. It is also a good conductor of heat. It has a low specific heat capacity i.e.140 J/Kg°C. So, it is used as a thermometric liquid.
