How a liquid-in-glass thermometer works
Liquid-in-glass thermometers are based on the principle of thermal expansion of substances. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion. Such … Ver mais The liquids used in such thermometers must have certain properties in order to be suitable for use. For example, they must not freeze at low temperatures, which is why water, for … Ver mais The measuring sensitivity of liquid-in-glass thermometers increases with the amount of liquid in the thermometer. The more liquid there is, the more liquid will expand and rise in the glass … Ver mais Mercury was/is used not only because of the wide temperature range (theoretically applicable from -39 °C to 357 °C) but also because mercury hardly wets the glass tube.
