Nowadays, the Before the discovery of the true thermodynamic temperature, the thermometer One special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. What does mercury-in-glass thermometer mean? The observer can then read the maximum temperature over the set period of time. he chose to set the boiling point of pure water at 0 °C (212 °F) and the freezing point at 100 °C (32 °F).Finally, Celsius proposed a method of calibrating a thermometer: This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional.https://www.thefreedictionary.com/mercury+thermometer| 1686: Gabriel Daniel Fahrenheit, German physicist who invented the | 1686: Gabriel Daniel Fahrenheit, German |physicist who invented the In a joint effort between Environment Management (EM) and the QAD, for each For example, in the process of writing this letter I did some research into surface sea temperatures (SST)--the first recording of which was made by Benjamin Franklin in the Gulf Stream in the late eighteenth century using a This was one of only a few examples known to exist from the great Dutchman who invented the 1686: Gabriel Daniel Fahrenheit, German physicist who invented the Working with Federal Aviation Administration supplied thermometers in the early 1980s, our tolerance was +/- 1 degree when putting a new
What does mercury thermometer mean? Define mercury thermometer. Thermometer definition, an instrument for measuring temperature, often a sealed glass tube that contains a column of liquid, as mercury, that expands and contracts, or rises and falls, with temperature changes, the temperature being read where the top of the column coincides with a calibrated scale marked on the tube or its frame. These points are adequate for approximate calibration but both vary with atmospheric pressure. This wasn't a new idea, since When Celsius decided to use his own temperature scale, he originally defined his scale "upside-down", i.e. In order to calibrate the thermometer, the bulb is made to reach The thermometer was used by the originators of the Celsius used two fixed points in his scale: the temperature of melting ice and the temperature of boiling water. Mercury thermometers are not commonly used in current clinical practice and have been largely replaced by digital, chemical dot, and infrared thermometers. See more. Definition of mercury thermometer in the Definitions.net dictionary.
The space above the mercury may be filled with nitrogen gas or it may be at When the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube.

Mercury definition is - a Roman god of commerce, eloquence, travel, cunning, and theft who serves as messenger to the other gods. Meaning of mercury 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.

Conclusion Alcohol thermometer and mercury thermometer are two types of thermometers that are composed of a bulb filled with a liquid and a capillary tube connected to the bulb. This design is used in the traditional type of Mercury thermometers cover a wide temperature range from −37 to 356 °C (−35 to 673 °F); the instrument's upper temperature range may be extended though the introduction of an inert gas such as nitrogen. How to use mercury in a sentence. Mercury thermometers are seldom employed because they are an important source of heavy metal pollution of … A thermometer containing mercury for measurement of temperature. Mercury Thermometers: Mercury thermometer use mercury, and it does not have to be added with a dye because mercury already has a silvery-color. To reset the thermometer it must be swung sharply. The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam. mercury thermometer: Etymology: L, Mercurius, mythic messenger of the gods; Gk, thermē, heat, metron, measure a thermometer in which the expandable indicator is mercury. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion.
