If mercury is above desired level, grasp tip of thermometer securely, stand away from solid objects, sharply flick wrist downward. A mercury-in-glass thermometer, also known as a mercury thermometer, was invented by German physicist Daniel Gabriel Fahrenheit in 1724 and is a thermometer consisting of mercury in a It will not enlarge when it solidifies, therefore, it doesn’t fracture the glass tube of the thermometer. Thermometers have myriad uses in science, engineering, industry, medical facilities and daily living. Mercury is a dedicated chemical source for thermometers due to the fact that it remains in liquid form throughout various temperatures. The Dangerous Effects! 1. An inert gas, mainly argon or nitrogen which is filled inside the thermometer above mercury to trim down its volatilization. Alcohol Thermometers can leak easily and wet the wall, leading less accurate and slow readings. depends on the purpose or application for which you want to use the thermometer. Traditional thermometers use thermometric liquids (i.e., alcohol, mercury) to measure temperature in body cavities -- orally, rectally, vaginally -- or at other axillary points, such as the underarm 1 2. “In the LIG thermometer the thermally sensitive element is a liquid contained in a graduated glass envelope. Mercury is difficult to clean and it can easily contaminate other surfaces after a thermometer breaks. The rest of the tube may be a vacuum, or it may be filled with nitrogen. Is It Dangerous?

It is very reflective, so it's easy to see and to read accurately. Later on, more linear thermometers were developed with the use of mercury as a liquid inside the thermometer. It also has a high boiling point.This video is about: Why Mercury is Used in Glass Thermometer.. The thermometer … The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. It is the presence of mercury (about 2 grams) – hazardous substances for health and glass design “thermometer” that can be easily broken up, negates all the advantages of mercury thermometer compared with all the others. The thermometer usually has a small reserve of liquid mercury in its base, which is most often pressurized; above it is usually a glass or synthetic tube with a calibrated temperature scale. Meaning of mercury-in-glass thermometer. The open end was immersed upside down in a mixture of alcohol with water and when heating the liquid, it went up the tube until it reached the sphere depending on the temperature.
