Evaporating Petri Syracuse Watch glass. Retrieved Degrees of Temperature The Celsius and Fahrenheit scales use degrees to measure temperature. Thus if the same type of thermometer is calibrated in the same way its readings will be valid even if it is slightly inaccurate compared to the absolute scale. Thermometers may be described as empirical or absolute. In , he proposed a temperature scale which now slightly adjusted bears his name.

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! Types of Thermometers Liquid Thermometers Liquid expands at a regular, measureable rate when it is heated.

A thermometer is a device that measures temperature the degree of hotness or coldness of an object or temperature gradient the rates of change of temperature in space, thermometer. A thermometer has two important elements: 1 thermometer temperature sensor e, thermometer. Thermometers are widely used in technology and industry to monitor processes, thermometer, 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. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers, thermometer. The most recent thermometer temperature scale is the International Temperature Scale of It extends from 0. Sparse and conflicting historical records make it difficult to pinpoint the invention of the thermometer to any single person or date with certitude. In addition, given the many parallel developments in the thermometer's history and thermometer many gradual improvements over time, thermometer, the instrument is best viewed not as a single invention, thermometer, but an evolving technology, thermometer. Early pneumatic devices and ideas from antiquity thermometer inspiration for thermometer thermometer's invention during the Renaissance period. In the 3rd century BC, thermometer, Philo of Byzantium documented his experiment with a tube submerged in a container of liquid thermometer one end and connected to an air-tight, hollow sphere on the other. When ceo pieluchy in the sphere is heated with a candle or by exposing it to the sun, expanding air exits the sphere and generates bubbles in the vessel. As air in the sphere cools, thermometer, a partial vacuum is created, sucking liquid up into the tube.
