At what temperature does water boil on the highest peak in the world - Chomolungme?

The boiling point - the phase transition from a liquid to a gaseous state (and vice versa) - of water, like any other substance, increases with increasing external pressure. At standard atmospheric pressure at sea level (101,3 kilopascals), the boiling point of water is 100 degrees Celsius.

At the highest peak in the world - Chomolungma, where the standard atmospheric pressure is 31,5 kilopascals, the boiling point of water is 69,7 degrees Celsius.

At a pressure equal to the pressure of water at a depth of 1 kilometer (9807 kilopascals), water boils at a temperature of 309,5 degrees Celsius.

 Random interesting fact from the Great Encyclopedia:

The translation of which book into the languages ​​of European peoples contributed to the creation of their national script and literary language?

This book is the Bible. So, in 350, Bishop Ulfilas translated a significant part of the Bible into the Gothic language, which laid the foundations of the Gothic literary language. Since the Gothic language did not have words for many Christian concepts, Ulfila had to not only invent new words, but even develop a special alphabet.

With the aim of translating the Bible into Armenian, the monk Mesrots Mashtop at the turn of the XNUMXth and XNUMXth centuries invented an original script so well adapted to the transmission of Armenian sounds that it has survived almost unchanged to this day.

In order to translate the Bible into Slavonic, the Byzantine missionaries Cyril and Methodius created the Slavic alphabet around 863. In 1522, the first part of the Bible was published in a German translation by Martin Luther.

Trying to make the translation accessible and understandable to as many compatriots as possible, Luther used the variant of the language, which, in his opinion, was not characterized by regional limitations, and thereby laid the foundation for the subsequent development of a common German literary language.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Bottle of wine in a proton accelerator 14.02.2009

French physicists from the Center for Nuclear Research in Bordeaux have learned how to determine the time of glass production by firing wine bottles with high-energy protons.

X-rays produced by proton impacts carry information about the chemical composition of the glass, and by comparing this composition with data from a collection of 80 bottles, the age and origin of which are precisely known, it is possible to determine when and where the bottle was made.

The process does not affect the quality and taste of the contents of the vessel. So far, the age of a bottle is determined with an accuracy of 15 years, but by expanding the collection of "reference" bottles, physicists hope to bring the accuracy up to two years. If the age of the bottle and the year of wine production indicated on the label differ greatly, we are talking about a fake.

Another group of researchers from the same Center dates the wine itself by determining the content of the caesium-137 isotope in it. This isotope occurs in nuclear explosions and accumulates in grapes, so the dating limit is limited to the period from 1945 to 1963, when atmospheric testing of nuclear weapons was prohibited. But the accuracy of the method is up to one year.
