: from French thermomètre or modern Latin thermometrum, from thermo- ‘of heat’ + -metrum ‘measure.’. For example, how do you explain the hotness of an object? "thermometer An analog thermometer consists of a sealed tube with markings on it. Thermistor is a device which becomes a much better electrical conductor when its temperature rises. Gale Encyclopedia of Surgery: A Guide for Patients and Caregivers, Gale Encyclopedia of Nursing and Allied Health. Step 1: Electrical conduction property is used in Thermistor type thermometer, so the choice "A" is wrong. 4 Once full, the tube is placed upon its bulb end. Encyclopedia.com. 5 After the tube is sealed, a scale is applied based on the level at which the fluid rests when inserted into a water bath of 212 degrees Fahrenheit (100 degrees Celsius) versus one at 32 degrees Fahrenheit (0 degrees Celsius).

Due to environmental concerns, contemporary thermometers are manufactured less with mercury and more with a spirit-filled hydrocarbon liquid. . C. 420C

Thermometer is a device used for measuring the temperature. A thermometer is a device used to monitor temperature. This method is used with infants. © 2019 Encyclopedia.com | All rights reserved. ." Encyclopedia.com. 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. "thermometer A gas thermometer is a thermometer that measures temperature by the variation in volume or pressure of a gas. 1 First, the raw glass material is received from an outside manufacturer. Oral or sublingual. When enclosures are used on the scales, a silkscreening process is used to apply the marks. Therefore, that information is unavailable for most Encyclopedia.com content. More technically, temperature indicates the direction in w…, Fahrenheit temperature scale There are different types of thermometer and some are electrical. The bulb is sealed at its bottom, leaving an open tube at the top. The Oxford Pocket Dictionary of Current English. Ink is then rubbed into the marks to highlight the scale values. Alternately, the bulb can be made by blowing a separate piece of lab material that is then joined with one end of the glass tube. This thermometer functions by Charles's Law. 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. Celsius •Bierce, fierce, Pearce, Peirce, pierce, tierce •Fabius, scabious •Eusebius •amphibious, Polybius •dubious…, Isotherm The bored tubes are checked for quality; any rejected parts are sent back to the manufacturer for replacement. 3 With the open end down in a vacuum chamber, air is then evacuated from the glass tube, and the hydrocarbon fluid is introduced into the vacuum until it penetrates the tube about 1 inch (2.54 centimeters). . The tip of a rectal mercury thermometer is usually colored blue to distinguish it from the silver tip of an oral/axillary thermometer. n. an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling. Volume Thermometer. Thermometer is a device used for measuring the temperature. In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Electrical conduction. Which property is used in mercury � in � glass thermometer?. The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics).
