Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer . Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition.

The temperature inside the human body is close to 37 °C or 98 °F. Water boils at 100 °C, 212 °F, or 373.15 K. Things begin to glow Red hot at approximately 550 °C, 1,000 °F, or 800 K. Things begin to glow White hot at about 1,300 °C, 2,400 °F, or 1,600 K. The coldest possible temperature is absolute zero.

Average yearly temperature is 22.4 degrees Celsius, ranging from an average minimum of 12.2 degrees to a maximum of 29.9 degrees. The average temperature range is 11.4 degrees. [7] Variability along the year is small (standard deviation of 2.31 for the maximum monthly average and 4.11 for the minimum).

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 local temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.

View history. A temperature coefficient describes the relative change of a physical property that is associated with a given change in temperature. For a property R that changes when the temperature changes by dT, the temperature coefficient α is defined by the following equation: Here α has the dimension of an inverse temperature and can be ...

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere. Weather refers to day-to-day temperature ...

1 thg 12, 2022 · temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; …
