The bulb is carefully designed to contain a calculated … Web12 de mai. de 2024 · Video advice: alcohol thermometer. Thermometers, usually made of glass, contain a narrow capillary tube and a liquid whose density changes predictably with temperature. The density of the material determines the volume it will occupy. When the liquid is heated its density decreases and it occupies more space.
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. The capillarity is … Ver mais Web10 de set. de 2024 · Air temperature is measured with thermometers. Common thermometers consist of a glass rod with a very thin tube in it. The tube contains a liquid that is supplied from a reservoir, or “bulb,” at the base of the thermometer. When you are measuring the air temperature, be sure to have the thermometer in the shade.
WebIn 1714, a Dutch inventor named Daniel G. Fahrenheit invented the first reliable thermometer that used mercury instead of other not-so reliable liquids used by prior inventors. This type of thermometer measured changes in the volume of mercury in a glass tube due to temperature changes [6].
