the temperature of liquid must be read while the thermometer is in liquid,so it doesn't have a kink

Kink also is called a constriction .


⊕ Constrictions present in a thermometer are used for the following


О Constrictions prevent the level of the thermometric liquid to suddenly fall after measuring the temperature.

О The constriction hence conserves the reading of the thermometer for a certain period of time after which it falls .

О This allows the user to get enough time to read the readings of the level of the thermometer.


Θ Kink is not present in lab thermometers.


ОThe absence of constrictions help to measure the temperature readings accurately .

О In a laboratory the thermometer is generally required for measuring different instances of a chemical reaction

О The chemical reaction may change the temperatures very abruptly.

О Thus constrictions should interrupt the accurate and rapid changes in the thermometer.

О This also helps to read temperature in liquids because the temperature should rapidly change in such a case.


→ That's why kink is not present in laboratory thermometer
