What else can I help you with?
What is the word equation for liquid helium?
There is no word equation, except that helium will exist as liquid phase in liquid helium
What effect does liquid nitrogen have on molecular kinetic energy?
Temperature is a measure of kinetic energy. Because liquid nitrogen is very cold, a system's kinetic energy will be collisionally transferred to the added liquid nitrogen. Thus, in general, adding liquid nitrogen will decrease a system's kinetic energy. (There are some exceptions where the system has less kinetic energy than the liquid nitrogen, such as liquid helium.)
What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
How is nitrogen gas sold?
As with most gasses, nitrogen is usually sold in metal canisters with a valve at the top (like the kind you see people filling baloons with Helium from). Alternately, liquid nitrogen is available for sale and comes in a sealed canister.
How do you separate nitrogen gas from a mixture of nitrogen gas and liquid nitrogen?
You can separate nitrogen gas from liquid nitrogen by allowing the liquid nitrogen to evaporate at room temperature or by heating it to increase the rate of evaporation. The nitrogen gas will separate from the liquid nitrogen as it evaporates, leaving behind the liquid nitrogen.
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 - liquid nitrogen or liquid heluim?
Liquid helium is a lot colder than liquid nitrogen.
What element cools mri magnets?
liquid helium
If liquid nitrogen freezes everything why is itself a liquid?
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
Why does then large hadron collider need helium?
Liquid helium is colder than anything else on the face of the Earth. They cool the magnets with helium so the wire they're made out of will superconduct - flow electricity with no resistance. The LHC's magnets use 1.5 million watts of power all tolled; imagine how much they would need if the wire had even a thousandth of an ohm per meter resistance!
Liquid nitrogen is -320 degrees does it have heat energy?
yes. It would cause liquid helium to boil if you mixed them.
How are He and Nitrogen different forms of matter?
There are classically three states of matter -- solid, liquid and gas. Helium and Nitrogen are gasses.
What are some examples of liquids that don't freeze?
Some examples of liquids that do not freeze at typical temperatures include liquid nitrogen, liquid helium, and liquid mercury.
What is the word equation for liquid helium?
There is no word equation, except that helium will exist as liquid phase in liquid helium
What is the coldest chemical You can buy?
The coldest chemical you can buy is likely liquid nitrogen, which has a boiling point of -196 degrees Celsius. Liquid nitrogen is commonly used in scientific research and industry for its extremely low temperature properties.
Is there a more common coolant besides liquid nitrogen to cool below 75K?
Helium is used but it is more expensive.
