Mercury thermometer (mercury-in-glass thermometer) for measurement of room temperature. [1]A thermometer is a device that measures temperature (the hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space).
A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...
The length of your fever will usually depend on what’s behind it, Dr. Russo says.“Individuals that have a self-limiting cause for a fever, such as a viral infection that you recover from may ...
A medical mercury-in-glass maximum thermometer showing the temperature of 38.7 °C (101.7 °F). One special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion.
Temperature is a measure of a quality of a state of a material. [39] The quality may be regarded as a more abstract entity than any particular temperature scale that measures it, and is called hotness by some writers.
