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 athermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
Alcohol:
as the temperature increases the liquid in the bulb expands and pushes higher into the glass tube. As is cools, it...Alcohol thermometers?are?used?rather than mercury?thermometers?in very cold regions because?alcohol?has a lower freezing point than mercury.

Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature.
