Which is the coldest gas on the Earth?
At three hundred and twenty-one degrees below zero, liquid nitrogen is colder than the most frigid Arctic night. It’s a cryogenic substance that would fit in with Triton’s weather better than our own. Nitrogen on Earth is usually a gas, but it’s possible to condense it into liquid form in the lab.
Which is the coolest gas in the world?
Helium – The coolest of all gases.
What is the coldest thing in the galaxy?
The coldest place in the universe is in the Boomerang Nebula, a cloud of dust and gases 5,000 light years from Earth. It has a temperature of -272°C (-457.6°F). It is formed by the rapid expansion of gas and dust flowing away from its central ageing star.
Is Neptune colder than Pluto?
Home » Space Questions » What is the coldest planet? The short answer is that Neptune has the coldest overall average temperature and Uranus has the coldest temperature recorded. Pluto was the planet furthest away from the Sun and also the coldest.
What is the hottest gas on Earth?
|Boiling point||76.5 °C (169.7 °F; 349.6 K)|
|Std enthalpy of formation (ΔfH⦵298)||+500.4 kJ/mol|

Which is the coldest gas in the world?
Scientists at the National Bureau of Standards have chilled sodium atoms to the lowest temperature ever recorded in a gas, 43 millionths of 1 degree Centigrade above the absolute zero.
Why is absolute zero the coldest gas in the universe?
The atoms in a liquid move a little slower. The atoms in a solid move so slowly that you cannot see movement. Absolute zero is so cold that the atoms do not move at all. Scientists can get a gas very cool. They can make it so cold that it is a different state of matter.
Which is the lowest temperature ever recorded in a gas?
Scientists at the National Bureau of Standards have chilled sodium atoms to the lowest temperature ever recorded in a gas, 43 millionths of 1 degree Centigrade above the absolute zero. Absolute zero, defined as the temperature at which all molecular motion ceases, is about 273.16 degrees below zero Centigrade,…
Which is the coldest place in the universe?
Absolute zero is the coldest. It is -459 F. Now that is cold! Everything is made of atoms. We cannot see them. All of the atoms are moving. Moving atoms make the states of matter.
