why is mercury used as a thermometric liquid?

♥ Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer

Advantages:-

♥ It is a good conductor of heat and therefore the whole liquid reaches the temperature of the surroundings quickly. -It does not wet (cling to the sides of) the tube. -It expands uniformly (linear expansion) and responds quickly to temperature changes, hence is sensitive.

Answer 2

Answer:

It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer.

The two advantages are:

1) Its durable.

2) It gives us accurate measure.

I hope it helps you. Have a good day/night ahead dear~
