why mercury is used in thermometer?

priy: it is a very high visocity

priy: mercury is a good condutor of heat

priy: it expands on heating

priy: mercury is only metal which is liquid

priy: at room temprature

shivacharu1: Thermometers made of different material (e.g., coloured alcohol thermometers) might be expected to give different intermediate readings due to different expansion properties; in practice the substances used are chosen to have reasonably linear expansion characteristics as a function of true thermodynamic temperature, and so give similar results.

Mercury has adequate thermal coefficient of expansion.it expands due to heat and as temperature increases.it is also a liquid at room temperature.it also does not stick to the glass tube.so,due to its expansive nature,mercury is used in thermometers.

Answer:

Mercury is the only one in liquid state at room temperature.It's used in thermometer because it has high coefficient of expansion.
