It can measure the temperature precisely, because it has large expansion coefficient. Since mercury has a higher boiling point than alcohol, mercury thermometer … The measurement range of alcohol thermometer depends on the boiling point of the liquid present in it. Cody'sLab Recommended for you. Both sensors are laying on top of the eggs. But if the capillary tube has nitrogen gas, then it increases the temperature range because nitrogen gas has the property of being inert, so it applies pressure on the mercury, which results in the rising of the boiling point of mercury. When using thermometers, there are several precautions to minimize the errors. The endurability of alcohol thermometers is relatively less because it is susceptible to evaporation, whereas the endurability of alcohol thermometers is high as mercury is resistant to evaporation. Alcohol thermometers have alcohol inside the bulb of the thermometer, whereas mercury thermometer has mercury enclosed in the bulb of a thermometer. 1. Und es gibt eine Skala, die die gemessene Temperatur anzeigt. Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly. $8.00 $ 8. The disposable "hat" of an ear thermometer can be replaced, and do not need to be soaked and disinfected. The alcohol present in the alcohol thermometers is colored using a dye such as blue or red, while the mercury present in the mercury thermometers already has a metallic silver color and doesn’t use any dye. The preference of alcohol thermometers as compared to the mercury thermometers is due to their secure and safe chemical compound. Thermometers have been in vogue for a v e ry significant period of time. Thermometer ist ein Gerät zur Temperaturmessung. Normalerweise werden die Temperaturen in Grad Celsius oder Grad Fahrenheit gemessen. For this reason, it's important to avoid handling the bulb when working with this type of thermometer, and to avoid exposing the bulb to temperature extremes when trying to get an accurate reading. But it becomes lethal in a gaseous state like inorganic salts and organomercuric compounds, and it has considerable toxic effects on fetuses, infants, and children. Earlier the mercury thermometers were considered gold standard. Toxicity of alcohol is less; thus, alcohol thermometers have a secure use; however, the toxicity of mercury is higher; therefore, mercury thermometer is less safe for use. Alcohol thermometers can measure comparatively low temperatures that range from -115-78.5°C (-117 to 173.3°F), while mercury thermometers can measure relatively high temperatures ranging from −37 to 356 °C (-34.6 to 672.8°F). Alcohol's low boiling point (79 °C) limits its use to meteorology and body temperature. The measurable temperature range varies according to the used fluid inside the bulb. Liquids such as pure alcohol, kerosene, and toluene can be present interior to the bulb of alcohol thermometer, but mercury is the only liquid that can be present inside the bulb of a mercury thermometer. well, thanks for this blog because right now I need the information about the differences between Mercury and Alcohol thermometer.. thank you so much! In 1714 invention of the mercury thermometer took place by a scientist named Daniel Gabriel Fahrenheit.
