  2. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Earth cutaway from core to exosphere Geothermal drill machine in Wisconsin, USA. Temperature within Earth increases with depth. Highly viscous or partially molten rock at temperatures between 650 and 1,200 °C (1,200 and 2,200 °F) are found at the margins of tectonic plates, increasing the geothermal gradient in the vicinity, but only the outer core is postulated to exist in a molten or fluid ...

  3. Superheated water - Wikipedia

    en.wikipedia.org/wiki/Superheated_water

    Water is a polar molecule, where the centers of positive and negative charge are separated; so molecules will align with an electric field.The extensive hydrogen bonded network in water tends to oppose this alignment, and the degree of alignment is measured by the relative permittivity.

  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"). [ 54 ] [ 5 ] [ 55 ] [ 56 ] 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. [ 57 ]

  9. British thermal unit - Wikipedia

    en.wikipedia.org/wiki/British_thermal_unit

    In the United States and Canada, the R-value that describes the performance of thermal insulation is typically quoted in square foot degree Fahrenheit hours per British thermal unit (ft 2 ⋅°F⋅h/Btu). For one square foot of the insulation, one Btu per hour of heat flows across the insulator for each degree of temperature difference across it.
