The above statement is true.
Clinical thermometers are used in the medical field. It was designed to measure a human's body temperature. It comprises a long, thin glass tube with a mercury-filled bulb at one end. To ensure a precise reading, the thermometer is given a few sharp jerks before usage, allowing the mercury level to flow into the bulb at a lower temperature than usual. As a result, the clinical thermometer is given a few quick jerks for correct reading because the mercury level pours into the bulb at a lower temperature than usual.
