The liquid in a glass thermometer, either colored alcohol or mercury, expands as it heats and condenses as it cools. In a thermometer, the liquid cannot expand outward and the only place it can go is up or down. Temperature on a glass thermometer can be measured in Fahrenheit, Celsius or Kelvin.Know More
Once a thermometer is built and filled with liquid, numbers are printed, usually along the outside. These numbers make it easy to determine the temperature of a person, home or even the outdoors.
Thermometers that do not use liquid use a spring mechanism that expands as it heats and contracts as it cools.Learn more about Thermodynamics
A thermometer is usually calibrated using two approaches: the ice point method and the boiling point method. This temperature measuring deviceÂ must be calibrated daily if repeatedly used. Otherwise, a thermometerÂ should be adjusted prior to itsÂ initial usage, when switching from one temperature to another or every time itÂ is dropped.Full Answer >
A clinical thermometer is a thermometer that has been designed to measure the human body's temperature; they are designed to detect temperatures a few degrees above and below the average human temperature (97.7 to 99.5 degrees Fahrenheit). Historically, clinical thermometers were generally mercury-filled, but modern thermometers are often digital.Full Answer >
To obtain an accurate temperature reading, a glass thermometer must remain in the mouth for three minutes, while a digital thermometer remains in the mouth until it beeps or the temperature reading appears in the window, according to Drugs.com. The tip of the thermometer must be placed under the tongue.Full Answer >
