2. Degree (temperature) - Wikipedia

   en.wikipedia.org/wiki/Degree_(temperature)

   Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Other scales of temperature:

3. Measure (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Measure_(mathematics)

   A simple example is a volume (how big an object occupies a space) as a measure. In mathematics, the concept of a measure is a generalization and formalization of geometrical measures (length, area, volume) and other common notions, such as magnitude, mass, and probability of events. These seemingly distinct concepts have many similarities and ...

4. Kelvin - Wikipedia

   en.wikipedia.org/wiki/Kelvin

   This definition assumes pure water at a specific pressure chosen to approximate the natural air pressure at sea level. Thus, an increment of 1 °C equals ⁠ 1 / 100 ⁠ of the temperature difference between the melting and boiling points. The same temperature interval was later used for the Kelvin scale.

5. Scale of temperature - Wikipedia

   en.wikipedia.org/wiki/Scale_of_temperature

   This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...

6. Temperature - Wikipedia

   en.wikipedia.org/wiki/Temperature

   If heat capacity is measured for a well-defined amount of substance, the specific heat is the measure of the heat required to increase the temperature of such a unit quantity by one unit of temperature. For example, raising the temperature of water by one kelvin (equal to one degree Celsius) requires 4186 joules per kilogram (J/kg).

7. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   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.

9. Heat equation - Wikipedia

   en.wikipedia.org/wiki/Heat_equation

   The temperature approaches a linear function because that is the stable solution of the equation: wherever temperature has a nonzero second spatial derivative, the time derivative is nonzero as well. The heat equation implies that peaks ( local maxima ) of u {\displaystyle u} will be gradually eroded down, while depressions ( local minima ...
