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.
Is anything colder than liquid nitrogen?
| Fluid Boiling temperature Celsius Boiling temperature Fahrenheit | Nitrogen -196° -320° | Neon -246° -411° | Hydrogen -253° -423° | Helium -270° -452° |

Which is the coldest liquid in the world?
Liquid hydrogen
is the coldest substance known to man, minus 400 degrees.
What's that really cold liquid?
The word “
cryogenic
” means “producing, or related to, low temperatures,” and all cryogenic liquids are extremely cold. Cryogenic liquids have boiling points below -150°C (- 238°F) (Carbon dioxide and nitrous oxide, which have slightly higher boiling points are sometimes included in this category).
Whats colder liquid nitrogen or oxygen?
Liquid nitrogen
has a lower boiling point at −196 °C (77 K) than oxygen's −183 °C (90 K), and vessels containing liquid nitrogen can condense oxygen from air: when most of the nitrogen has evaporated from such a vessel, there is a risk that liquid oxygen remaining can react violently with organic material.
What is the hottest liquid on Earth?
Now we know from experiments at RHIC and at the Large Hadron Collider that at these extreme temperatures nature serves up
hot quark soup —
the hottest liquid in the universe and the liquid that flows with the least dissipation.
What's the hottest thing on Earth?
The hottest thing that we know of (and have seen) is actually a lot closer than you might think. It's right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches
7.2 trillion degrees Fahrenheit
. That's hotter than a supernova explosion.
Can you drink liquid nitrogen?
Safety concerns. Because of its low temperature liquid nitrogen can be extremely damaging to body tissue, causing frostbite and cryogenic burning on contact. If ingested it can lead to severe internal damage, destroying tissue in the mouth and digestive tract.
What happens if you touch liquid nitrogen?
Liquid nitrogen has a boiling temperature of -196°C at atmospheric pressure. Direct contact can
freeze the skin causing frostbite and cold burns
. Delicate tissue, such as eyes, can be damaged by an exposure to the cold gas alone which would be too brief to affect skin.
Can I buy liquid helium?
We offer helium in high-pressure gas cylinders and liquid dewars—available in a variety of sizes—to meet any and all low-volume needs. Helium is also available in bulk gas and liquid
delivery
, as well as in a full range of purities and tank sizes.
What is the coolest liquid?
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.
Is liquid oxygen bad for you?
* Contact with liquid Oxygen can
cause severe skin and eye irritation and burns as
well as frostbite. * Breathing pure Oxygen at high pressures can cause nausea, dizziness, muscle twitching, vision loss, convulsions (fits), and loss of consciousness.
Can you make liquid air?
Process of manufacturing. The most common process for the preparation of liquid air is the
two-column Hampson–Linde cycle using the Joule–Thomson effect
. Air is fed at high pressure (>75 atm (7,600 kPa; 1,100 psi)) into the lower column, in which it is separated into pure nitrogen and oxygen-rich liquid.
What are the advantages of liquid oxygen?
The primary benefit of liquid oxygen is that
continuous flow oxygen can be supplied in a relatively small, lightweight container
. The key advantages of liquid oxygen include portable, continuous flow capability, 100% concentrated oxygen, low weight (less than 10 pounds), and long duration (over 18 hours).
Which is the coolest gas in the world?
Helium
– The coolest of all gases.
Can we drink liquid oxygen?
Oxygenated water is similar to hydrogen peroxide, a common antiseptic agent. Both liquids are forms of oxygenated water, though in hydrogen peroxide, a bond exists between two oxygen molecules. On the other hand, oxygenated water is
simply oxygen dissolved in water
, which is safe to drink.
