Of the ELEMENTS, Helium has both the lowest melting point and the lowest boiling point. Under normal pressure, Helium is only a liquid between -272C and -269C. That first number is less than one degree above absolute zero, so there's not much room for any compound to be a colder liquid.

What is colder - liquid nitrogen or liquid heluim?
Liquid helium is colder than liquid nitrogen. Liquid nitrogen boils at -196°C, while liquid helium boils at -269°C.
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
What liquid has lowest density?
kerosene
What is helium's natural state of matter?
Helium is a noble gas that exists in a gaseous state at room temperature and pressure. It only becomes a liquid or solid at extremely low temperatures.
What temperature is helium a liquid?
Helium becomes a liquid at temperatures below -268 degrees Celsius, which is referred to as its boiling point.
What is colder - liquid nitrogen or liquid heluim?
Liquid helium is colder than liquid nitrogen. Liquid nitrogen boils at -196°C, while liquid helium boils at -269°C.
What is colder helium or hydrogen?
Helium is colder than hydrogen at the same temperature because helium has a lower boiling point (-268.9 degrees Celsius) compared to hydrogen (-252.9 degrees Celsius).
Is liquid nitrogen colder than nitrogen gas?
At the same pressure yes, liquid nitrogen is colder than gaseous nitrogen.
Is liquid methane colder than liquid nitrogen?
Yes, liquid methane is colder than liquid nitrogen. Liquid methane has a boiling point of around -161 degrees Celsius, while liquid nitrogen has a boiling point of around -196 degrees Celsius.
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
What is colder than freezing?
There is nothing colder than freezing, as freezing is the temperature at which a substance changes from a liquid to a solid.
What is the word equation for liquid helium?
The word equation for liquid helium is: Helium gas → Liquid helium.
Which liquid boils the quickest?
Liquid helium in the helium I phase boils at about 5 K, lower than any other substance. (Liquid helium in the helium II phase does not boil, it simply evaporates. Helium is truly weird stuff at very low temperatures.)
What liquid has lowest density?
kerosene
Is liquid nitrogen the coldest substance on earth?
The coldest matter in the world is a Bose-Einstein condensate of atoms that have been cooled to within tiny fractions of a kelvin of absolute zero (-273 C). The coldest material generally available is liquid nitrogen (temperature - 196 C, - 320 F). The coldest place on Earth is the Antarctic Plateau, with temperatures as low as -90 C (-129 F). One of the coldest naturally-occurring things on Earth is ice formed at very high pressures, with temperatures down to -140 C.
Is water the lightest liquid on earth?
No, water is not the lightest liquid on Earth. Liquid hydrogen and liquid helium are lighter than water because they have lower densities.
Is liquid helium a true substance?
Yes, liquid helium is a true substance. It is the liquid form of the element helium, which is a noble gas. At very low temperatures close to absolute zero, helium gas condenses to form liquid helium, exhibiting unique physical properties and behaviors.
