Question

which liquid is used in a clinical thermometer​

Answer 1

Answer:

Mercury

Explanation:

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

Answer 2

Mercury.

• The most accurate liquid-filled thermometers have been mercury-in-glass thermometers.

• Mercury, on the other hand, is a poisonous heavy metal, and it has only been used in clinical thermometers provided the tube is shielded against fracture.

Explanation:

To minimize the amount of mercury in the tube—the temperature of the tube is not controlled, so it must contain much less mercury than the bulb to minimize the effect of the tube's temperature—the tube must be very narrow, which makes reading difficult because the narrow mercury column is not very visible. With a colored liquid, visibility is less of an issue.

Many jurisdictions have banned the use and sale of mercury thermometers owing to the dangers of handling and leaking mercury, as well as the risk of mercury poisoning; the forceful swinging required to "reset" a mercury maximum thermometer makes it possible to shatter it and release dangerous mercury fumes.
