  2. Negative temperature - Wikipedia

    en.wikipedia.org/wiki/Negative_temperature

    Other degrees of freedom, such as molecular vibrational, electronic and electron spin levels are at a positive temperature, so the object still has positive sensible heat. Relaxation actually happens by exchange of energy between the nuclear spin states and other states (e.g. through the nuclear Overhauser effect with other spins).

  3. Orders of magnitude (temperature) - Wikipedia

    Maximum safe temperature for hot water according to numeric U.S. plumbing codes [48] Water will cause a second-degree burn after 8 minutes and a third-degree burn after 10 minutes [ 48 ] 323.14 K

  4. Kelvin - Wikipedia

    It may be in plural form as appropriate (for example, "it is 283 kelvins outside", as for "it is 50 degrees Fahrenheit" and "10 degrees Celsius"). [ 57 ] [ 5 ] [ 58 ] [ 59 ] The unit's symbol K is a capital letter, [ 39 ] per the SI convention to capitalize symbols of units derived from the name of a person. [ 60 ]

  5. Climate sensitivity - Wikipedia

    en.wikipedia.org/wiki/Climate_sensitivity

    A fifth of the models began to 'run hot', predicting that global warming would produce significantly higher temperatures than is considered plausible. [ 116 ] [ 117 ] According to these models, known as hot models , average global temperatures in the worst-case scenario would rise by more than 5 °C above preindustrial levels by 2100, [ 118 ...

  6. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    In the hot season, solar radiation predominates as the source of heat gain. According to the Stefan–Boltzmann law, radiative heat transfer is related to the fourth power of the absolute temperature (measured in kelvins: T [K] = T [°C] + 273.16). Therefore, such transfer is at its most significant when the objective is to cool (i.e. when ...

    Autumn in Eagle River AK. Average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); [4] average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). [4]

  8. Hail - Wikipedia

    en.wikipedia.org/wiki/Hail

    Research focused on four individual days that accumulated more than 5.9 inches (15 cm) of hail in 30 minutes on the Colorado front range has shown that these events share similar patterns in observed synoptic weather, radar, and lightning characteristics, [60] suggesting the possibility of predicting these events prior to their occurrence. A ...
