Why is the gas thermometers is more sensitive than the liquid thermometer? -Do You Know?

Description : Why is the gas thermometers is more sensitive than the liquid thermometer? -Do You Know?

Last Answer : answer:

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.
