Essay on Types of Thermometer Different types of thermometers Galileo thermometer. A Galileo thermometer (or Galilean thermometer), named after Italian physicist Galileo Galilei, is.
Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer, the modern thermometer. By the time Thomas Clifford Allbutt was a young man, the thermometer was commonly used to monitor sick patients.
The clinical or medical thermometer was modified with a sharp bend in its tube that was narrower than the rest of the tube. This narrow bend kept the temperature reading in place after you removed the thermometer from the patient by creating a break in the mercury column.
A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature.The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature.
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object) A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this.
Mercury expands when warmed and thus indicates temperature. Electron mobility in semiconductor is similarly influenced but more easily scaled and thus makes a better thermometer. A mercury thermometer routes the expanding liquid from the reservoir bulb into a narrow and uniform passage, optically magnified by the surrounding glass, to provide visible motion agains an engraved scale.
This thermometer consists of a glass bulb and stem filled with a working liquid (alcohol or mercury) and an inert gas. When the temperature changes, the liquid expands or shrinks. When paired with a temperature scale, it is possible to use this occurrence to determine the temperature.
A mercury thermometer has a bulb with a capillary tube attached to it surrounded by glass tube casing on which degrees are mentioned. SO, when its bulb having mercury filled in it ,come in touch with something hotter or colder or even having mode.
Mercury filled: mercury thermometers used to be the household item for measuring body temperatures, but according to US News, it has been phased out for commercial use. If the thermometer is accidentally broken, the liquid and the fumes it emits are extremely toxic to both humans and the environment.
The Physics Classroom Tutorial presents physics concepts and principles in an easy-to-understand language. Conceptual ideas develop logically and sequentially, ultimately leading into the mathematics of the topics. Each lesson includes informative graphics, occasional animations and videos, and Check Your Understanding sections that allow the user to practice what is taught.
Who invented the thermometer. The first recorded thermometer was produced by the Italian, Santorio Santorio (1561-1636) who was one of a group of Venetian scientists working at the end of the Sixteenth Century. As with many inventions the thermometer came about through the work of many scientists and was improved upon by many others.
Electronic thermometers. One problem with mercury and dial thermometers is that they take a while to react to temperature changes. Electronic thermometers don't have that problem: you simply touch the thermometer probe onto the object whose temperature you want to measure and the digital display gives you an instant temperature reading.
Mercury, the liquid used in analog thermometers, is extremely toxic and is capable of killing. If the glass tube thermometer breaks, it could result in cuts and makes for an extremally difficult mess to clean up due to the mercury. Digital thermometers, however, contain no mercury and are not toxic.
As anyone who’s ever broken a thermometer can attest, mercury is a fascinating substance. It also has an interesting history. Named after the fleet-footed Roman messenger of the gods, mercury has been used for more than 2,000 years.
Essay Mercury Mercury is a metallic element that is a liquid at room temperature, it is one of the transition elements. Mercury's atomic number is 80. It is superconductive when cooled to within a few degrees of absolute zero. Mercury was once known as liquid silver or quicksilver which was studied by the alchemists. Mercury was first distinguished as an element by the French chemist Antoine.Laboratory Thermometer. Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.Mercury, (HG) is a most unusual metal. It is the only common metal that occurs as a liquid at room temperature. This bright silvery, dense liquid- formerly known as quicksilver- has long held the fascination of people. Children sometimes play with the mercury from a broken thermometer, often with tr.
