Explanation: Mercury is a bad conductor of heat. It is used in different transparent meters because:
It has more cohesion than adhesion i.e. it does not stick to the walls of the tube.
It is shiny in colour and bulging out meniscus, so easier to look from outside the flask and give correct reading.
It expands with small change of temperature.
