The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
134 K, highest-temperature superconductor at ambient pressure, mercury barium calcium copper oxide; 165 K, glass point of supercooled water; 184.0 K (–89.2 °C), coldest air recorded on Earth; 192 K, Debye temperature of ice; 273.15 K (0 °C), melting point of bound water; 273.16 K (0.01 °C), temperature of triple point of water; c. 293 K ...
Highest dew point temperature: A dew point of 35 °C (95 °F) — while the temperature was 42 °C (108 °F) — was observed at Dhahran, Saudi Arabia, at 3:00 p.m. on 8 July 2003. [ 200 ] Highest heat index : In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F).
δ 18 O, a proxy for temperature, for the last 600,000 years (an average from several deep sea sediment carbonate samples) [a]. The 100,000-year problem (also 100 ky problem or 100 ka problem) of the Milankovitch theory of orbital forcing refers to a discrepancy between the reconstructed geologic temperature record and the reconstructed amount of incoming solar radiation, or insolation over ...
Temperature Range: 110 - 313 K; Max. Reynolds number: 50 million per m; Optical access to the test section for various cameras and light sources is provided through 90 special windows in all walls. [2]
For real gasses, the molecules do interact via attraction or repulsion depending on temperature and pressure, and heating or cooling does occur. This is known as the Joule–Thomson effect . For reference, the Joule–Thomson coefficient μ JT for air at room temperature and sea level is 0.22 °C/ bar .
Radio-telescope images taken in 1998 confirm that Betelgeuse has a highly complex atmosphere, [166] with a temperature of 3,450 ± 850 K, similar to that recorded on the star's surface but much lower than surrounding gas in the same region. [166] [167] The VLA images also show this lower-temperature gas progressively cools as it extends outward ...
[24]: 322 At that time, mean global temperatures were about 2–4 °C (3.6–7.2 °F) warmer than pre-industrial temperatures. The global mean sea level was up to 25 metres (82 ft) higher than it is today. [25]: 323 The modern observed rise in temperature and CO 2 concentrations has been rapid. Even abrupt geophysical events in Earth's history ...
