Question
What are the disadvantages of using mercury as a thermometric liquid?
Solution
The disadvantages of mercury as thermometric liquid are:
i) its temperature coefficient of expansion is very low and it cannot be used to measure the temperature below –39°C and above 357°C.
ii) Mercury thermometer cannot be used in very cold regions like arctic regions because it freezes below a temperature of 39o C.
