Other liquids, such as kerosene or ethanol , may also be used in these types of thermometers. The most recent official temperature scale is the International Temperature Scale of A maximum thermometer is a familiar type of liquid thermometer. Fraser, Ph. Analytical chemistry. A - Z health services visit a - z health services pharmacy first. Device to measure temperature. Alcohols, such as ethanol, boil at about 78 degrees Celsius degrees Fahrenheit. The best known of these fixed points are the melting and boiling points of pure water. North Carolina State University.
Thermodynamics , second edition revised by K. That is, does the same thermometer give the same reading for the same temperature or do replacement or multiple thermometers give the same reading? As body temperature varies, the Fahrenheit scale was later changed to use an upper fixed point of boiling water at °F °C. Ring January ISSN Authority control databases. For example, the expansion of mercury in a glass thermometer is slightly different from the change in resistance of a platinum resistance thermometer, so these two will disagree slightly at around 50 °C.

Geography, Physical Geography. A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food , a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system. The metric system of measurement also includes units of mass , such as kilograms, and units of length, such as kilometers. The metric system, including Celsius, is the official system of measurement for almost all countries in the world. Most scientific fields measure temperature using the Celsius scale. Zero degrees Celsius is the freezing point of water, and degrees Celsius is the boiling point of water. Three nations do not use the Celsius scale. However, even in these countries, scientists use the Celsius or kelvin scale to measure temperature. Water freezes at 32 degrees Fahrenheit and boils at degrees Fahrenheit. The Kelvin scale is used by physicists and other scientists who need to record very precise temperatures. The kelvin scale is the only unit of measurement to include the temperature for " absolute zero ," the total absence of any heat energy. This makes the kelvin scale essential to scientists who calculate the temperature of objects in the cold reaches of outer space. Water freezes at kelvins, and boils at kelvins. We do not read outdoor temperatures in the kelvin scale because it uses such large numbers—a degree Fahrenheit day would be read as kelvins!

A thermometer is a device thermometer measures temperature the degree of hotness or coldness of an object or temperature gradient the rates of change of temperature in space. A thermometer has two important elements: 1 a temperature sensor thermometer. Thermometers are thermometer used in technology and industry to monitor processes, in meteorologyin medicine medical thermometerand in scientific research. While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale, thermometer, thermometer. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, thermometer, based on fixed points and interpolating thermometers. The most recent official temperature scale is the International Temperature Scale of It extends from 0. Sparse and conflicting historical records make it inglesina huggy opinie to pinpoint thermometer invention of the thermometer to any single thermometer or date with certitude. In addition, thermometer, given the many parallel developments in the thermometer's history and its many gradual improvements over time, thermometer, the thermometer is best viewed not as a single thermometer, but an evolving technology, thermometer. Early pneumatic devices and ideas from antiquity provided inspiration for the thermometer's invention during the Renaissance period. In the 3rd century BC, Philo of Byzantium documented his experiment with a tube submerged in a container of liquid on one thermometer and connected to an air-tight, hollow sphere on the other.
