The American Heritage Dictionary of the English Language identifies room temperature as around 20–22 °C (68–72 °F; 293–295 K), [1] while the Oxford English Dictionary states that it is "conventionally taken as about 20 °C (68 °F; 293 K)". [2] Ideal room temperature varies vastly depending on the surrounding climate.
Temperature is a physical quantity that quantitatively expresses the ... The customarily stated minimalist version of such a law postulates only that all bodies ...
[16] Specifically, Thomson expressed the amount of work necessary to produce a unit of heat (the thermal efficiency) as () (+) /, where is the temperature in Celsius, is the coefficient of thermal expansion, and () was "Carnot's function", a substance-independent quantity depending on temperature, [17] motivated by an obsolete version of Carnot ...
Similar to the Kelvin scale, which was first proposed in 1848, [1] zero on the Rankine scale is absolute zero, but a temperature difference of one Rankine degree (°R or °Ra) is defined as equal to one Fahrenheit degree, rather than the Celsius degree used on the Kelvin scale.
where is the Boltzmann constant and is the temperature in Kelvin. [2] At room temperature, the Landauer limit represents an energy of approximately 0.018 eV (2.9 × 10 −21 J). As of 2012, modern computers use about a billion times as much energy per operation. [3] [4]

However, the deepest cryogenic points are based exclusively on the vapor pressure/temperature relationship of helium and its isotopes whereas the remainder of its cold points (those less than room temperature) are based on triple points. Examples of other defining points are the triple point of hydrogen (−259.3467 °C) and the freezing point ...
