Temperature is a physical quantity that quantitatively expresses the attribute of hotness or ... the total number of microstates in the combined system 1 + system 2 ...
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [ 7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [ 8] The theoretical maximum possible ground surface temperature has been ...
Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [ 8][ 9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
Biot number. The Biot number ( Bi) is a dimensionless quantity used in heat transfer calculations, named for the eighteenth-century French physicist Jean-Baptiste Biot (1774–1862). The Biot number is the ratio of the thermal resistance for conduction inside a body to the resistance for convection at the surface of the body.
The following table lists the highest and lowest temperatures recorded in the 50 U.S. states, the District of Columbia, and the 5 inhabited U.S. territories during the past two centuries, in both Fahrenheit and Celsius. [ 1] If two dates have the same temperature record (e.g. record low of 40 °F or 4.4 °C in 1911 in Aibonito and 1966 in San ...
The "degree Kelvin" (°K) is a former name and symbol for the SI unit of temperature on the thermodynamic (absolute) temperature scale. [ 1] Since 1967, it has been known simply as the kelvin, with symbol K (without a degree symbol). [ 2][ 3][ 4] Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but ...
In fluid mechanics, the Rayleigh number ( Ra, after Lord Rayleigh [ 1]) for a fluid is a dimensionless number associated with buoyancy -driven flow, also known as free (or natural) convection. [ 2][ 3][ 4] It characterises the fluid's flow regime: [ 5] a value in a certain lower range denotes laminar flow; a value in a higher range, turbulent ...
Burner is a mobile application for iOS and Android made by Ad Hoc Labs, Inc. that allows users to create temporary disposable phone numbers in the U.S. and Canada. [1] The app allows smartphone users to have a phone number that is anonymous and can be thrown away, for purposes such as online ads, while traveling, for business projects, or for dating profiles.
