Why Mercury is used in thermometers ?
by

1 Answer

Answer :

Mercury is a liquid metal. The heat causes a balanced and rapid rise in mercury , which is a necessary feature for measuring temperature. In addition, the melting point of mercury is much lower than the melting point of water and the boiling point is much higher than the boiling point of water. For this, mercury thermometers are mostly used to measure the body temperature.

Gas thermometers are more sensitive than the liquid thermometers because the gases – (1) have large coefficient of expansion (2) are lighter (3) have low specific heat (4) have high specific heat

Description : Gas thermometers are more sensitive than the liquid thermometers because the gases – (1) have large coefficient of expansion (2) are lighter (3) have low specific heat (4) have high specific heat

Last Answer : (1) have large coefficient of expansion Explanation: Gases are more sensitive to the temperature than liquids (such as mercury). That means gas expands more than the mercury for the same increase of temperature. Hence the has thermometer is more sensitive than liquid (mercury) thereto-meter.
