Pressure "landmarks": typical pressures reached by large-volume presses are up to 30–40 GPa, pressures that can be generated inside diamond anvil cells are ~1000 GPa, [2] pressure in the center of the Earth is 364 GPa, and highest pressures ever achieved in shock waves are over 100,000 GPa. [3]
A below-sea-level surface pressure record of 1,081.8 hPa (31.95 inHg) was set on 21 February 1961. [13] The lowest non-tornadic atmospheric pressure ever measured was 870 hPa (0.858 atm; 25.69 inHg), set on 12 October 1979, during Typhoon Tip in the western Pacific Ocean. The measurement was based on an instrumental observation made from a ...
On 26 January 1884, during the Ochtertyre storm the Ben Nevis summit weather station recorded a low pressure of 784.7 hPa (at high altitude (above 750 m) and not reduced to sea level) this is proposed as being almost certainly the lowest surface pressure ever recorded in the UK, [66] though due to altitude and not being a value reduced to sea ...
3 S at 150 GPa (around 1.5 million times atmospheric pressure) in a diamond anvil cell. [8] The critical temperature is 203 K (−70 °C) which would be the highest T c ever recorded and their research suggests that other hydrogen compounds could superconduct at up to 260 K (−13 °C). [9] [10]
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [8] The theoretical maximum possible ground surface temperature has been ...
In elementary schools and secondary schools, a 5-point grading scale is used: 5 (odlično, excellent, A) 4 (prav dobro, very good, B) 3 (dobro, good, C) 2 (zadostno, sufficient, D) is the lowest passing grade. 1 (nezadostno, insufficient, F) is the lowest possible grade, and the failing one. Grade. Letter Grade.
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For few years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
