2. Mercury-in-glass thermometer - Wikipedia

   en.wikipedia.org/wiki/Mercury-in-glass_thermometer

   As the temperature rises, the mercury is pushed up through the constriction by the force of expansion. When the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. The observer can then read the maximum temperature over the set period of time.

3. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...

4. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer. Other important devices for measuring temperature include:

5. Six's thermometer - Wikipedia

   en.wikipedia.org/wiki/Six's_thermometer

   The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature and should be the same on both scales. If the two readings are not the same, then the instrument scales are not correctly positioned or the instrument is damaged.

6. Temperature - Wikipedia

   en.wikipedia.org/wiki/Temperature

   Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measured with a thermometer.It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.

8. Galileo thermometer - Wikipedia

   en.wikipedia.org/wiki/Galileo_thermometer

   A Celsius Galilean thermometer in two degree gradations. A risen orange orb denotes 24 °C. A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the ...
