Answer has 13 votes. Liquid air. It is the coldest substance known. It takes an intense cold to produce it, and it has to remain cold much as ice is cold, only very much more so, as long as it is liquid air.
What liquid is the coldest?
Liquid helium
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 nitrogen the coldest substance?
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.
What liquid is colder than water?
Ice CAN be colder than water but melting ice IS the same temperature as the water., 0C. The process works like this: When supplying heat to ice colder than 0C the ice heats up till 0C. At 0C the ice starts melting into water of 0C.
Which is the hottest substance in the world?
Laser experiments shedding light on ultradense plasma. By zapping a piece of aluminum with the world’s most powerful x-ray laser, physicists have heated matter to 3.6 million degrees Fahrenheit (2 million degrees Celsius)—making it briefly the hottest thing on Earth.
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.
What is the hottest liquid on Earth?
quark soup —
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.
Can liquid nitrogen kill you?
Deaths by liquid nitrogen are not unheard of and usually arise out of asphyxiation as a result of the gas displacing oxygen in the body. If this happens, it can displace oxygen and cause unconsciousness or even death. Locations that utilize nitrogen in this form are often well-ventilated to prevent this.

Can you drink 0 degree water?
Yes, water can stay liquid below zero degrees Celsius. When we apply pressure to a liquid, we force the molecules to get closer together. They can therefore form stable bonds and become a solid even if they have a higher temperature than the freezing point at standard pressure.
Which is the material with the lowest freezing point?
The material with the lowest freezing point is helium. Under typical pressures, it does not freeze at all, even at temperatures approaching absolute zero. The reasons why are dictated by quantum mechanics: the zero point energy of a helium system is too great to allow freezing.
Which is the point at which liquid water condenses?
The dew point is the point at which liquid water would condense from the atmosphere, and the frost point is the temperature at which ice would form from the atmosphere.
Which is the lowest possible temperature in the world?
The lowest possible temperature, or absolute zero as it is called, is -459.67°F (-273.15°C). It is also called 0 kelvin , a scale with increments equivalent to degrees of Celsius, but which uses absolute zero rather than water’s freezing point as its starting point.
Which is the best type of water to use?
Attaches to your straw lid bottle, and lasts up to 3 months or 300 gallons per use. . Dark Roasts are the best. Try it for yourself. Available ground or whole bean.
