  2. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness.Temperature is measured with a thermometer.It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.

  3. Dothistroma septosporum - Wikipedia

    en.wikipedia.org/wiki/Dothistroma_septosporum

    The ideal germination temperature is 12–18 °C, with high levels of humidity. [14] The needles will then begin to show signs of infection, and eventually the pathogen produces stromata, which is the pathogen's fruiting body. These are formed in the spring and early summer, and usually coincide with above average levels of rainfall. [15]

  4. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere .

  5. Thermal physics - Wikipedia

    en.wikipedia.org/wiki/Thermal_physics

    Thermal physics, generally speaking, is the study of the statistical nature of physical systems from an energetic perspective. Starting with the basics of heat and temperature, thermal physics analyzes the first law of thermodynamics and second law of thermodynamics from the statistical perspective, in terms of the number of microstates corresponding to a given macrostate.

  6. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    The photosphere of the Sun, for instance, has an effective temperature of 5772 K as adopted by IAU 2015 Resolution B3. Digital cameras and photographic software often use colour temperature in K in edit and setup menus. The simple guide is that higher colour temperature produces an image with enhanced white and blue hues.

  7. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...

  8. Cold and heat adaptations in humans - Wikipedia

    en.wikipedia.org/wiki/Cold_and_heat_adaptations...

    Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).

  9. Thermal neutral zone - Wikipedia

    en.wikipedia.org/wiki/Thermal_neutral_zone

    In horses, the lower critical temperature is 5 °C while the upper critical temperature depends on the definition used. [11] Their thermoneutral zone is roughly 5–30 °C (41–86 °F). [12] In mice, the lower critical temperature and upper critical temperature can be the same, creating a thermoneutral point instead of a thermoneutral zone.
