Explanation:
Mercury is 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. In a mercury thermometer, a glass tube is filled with mercury and a usual temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts and the temperature can be read from the scale.
