What is the coldest natural thing on earth?
The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements..
What is the coldest gas?
Liquid helium has a boiling point of -452 degrees F below zero; it is the coldest material known. It is also the only material on earth that never exists as a solid, only as a cryogenic liquid and as a gas.
How hot can a human survive?
Hot. 44 °C (111.2 °F) or more – Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). 43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions and shock. Cardio-respiratory collapse will likely occur.
Which is the hottest gas?
Combustion of acetylene with oxygen produces a flame of over 3,600 K (3,330 °C; 6,020 °F), releasing 11.8 kJ/g. Oxyacetylene is the hottest burning common fuel gas.
Is Absolute Zero Possible?
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.
Is 0 Kelvin possible?
On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. … At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears.
Can liquid hydrogen kill you?
Liquid hydrogen wouldn’t be as reactive, but it the extreme cold and rapid expansion would do a lot of damage, and I’d guess it would be at least as deadly as drinking liquid nitrogen.
What is the hottest place on earth?
In July 1913, observers in Furnace Creek, California—Death Valley—watched the thermometer reach 56.7°C (134°F) and declared it to be the highest temperature ever recorded on Earth.

Do humans live in Death Valley?
More than 300 people live year-round in Death Valley, one of the hottest places on Earth. … With average daytime temperatures of nearly 120 degrees in August, Death Valley is one of the hottest regions in the world.
What is the oldest thing in the universe?
The search for extremely distant galaxies continues today. Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
What is the coldest substance known to man?
Liquid hydrogenLiquid hydrogen is the coldest substance known to man, minus 400 degrees. ALSO: A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 K, ?
What is the coldest thing in existence?
The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. Outflows of gas, streaming out from the central dying star, reach temperatures below -270 degrees Celsius.

Can liquid nitrogen kill you?
The fact is liquid nitrogen is dangerous if not handled properly. It can cause frostbite or cryogenic burns and if used or spilled in a confined space, liquid nitrogen – which is colourless, odourless and tasteless – can kill you.
What is the coldest ice in the world?
About minus 144°F, according to recent satellite measurements of the coldest known place on the planet. Scientists recorded this extreme temperature on the ice sheet deep in the middle of Antarctica during the long, dark polar winter.
