Liquid nitrogen is colder than liquid oxygen. You use the liquid nitrogen to chill the oxygen in the air and liquid oxygen will form. Liquid water and dry Ice (CO2) should also form due to their presence as well, but not in large quantity.
WARNING!! High concentrations of oxygen should be considered dangerous. When exposed to a small ignition source, it can cause flammable materials to combust much like an explosion, and will cause normally non flammable materials to burn readily. Human flesh burns better than wood after being exposed to 100% oxygen for a period of time. Please be careful.
At room temperature: Oxygen & Nitrogen are gases, Carbon is solid, & Mercury is a liquid.
Liquid nitrogen and oxygen are transported as liquids into space because they have a higher density in liquid form, allowing more of these gases to be packed into the spacecraft's tanks. This is important for providing sufficient breathable air and cooling systems for astronauts during space missions. Additionally, liquid nitrogen and oxygen have to be kept at very low temperatures for storage, and transporting them as liquids helps maintain those temperatures more effectively.
The answer is, liquid nitrogen ISN'T used in beer cans. Nitrogen GAS is. And the reason nitrogen gas is used in beer cans is to emulate draft beer such as one would get out of a keg(as opposed to cask) beer.
Argon is obtained by fractional distillation of liquid air, where it is separated from other gases such as nitrogen and oxygen. It is a byproduct of the production of liquid oxygen and liquid nitrogen.
Inhaling liquid nitrogen can cause serious harm to the respiratory system, including frostbite in the lungs and potentially fatal damage. It can also displace oxygen in the air, leading to asphyxiation. Immediate medical attention is necessary if liquid nitrogen is inhaled.
No. The wind is composed of a small amount of water vapor and about 20% oxygen and about 80% nitrogen. The water vapor may freeze but the oxygen and the nitrogen cannot freeze at the temperature of liquid nitrogen. Oxygen has a much lower freezing point than liquid nitrogen and if the nitrogen were to be frozen, liquid nitrogen is not cold enough to freeze it...sort of like trying to make ice using cold water.
dry ice −56.4 °C and liquid nitrogen is −196 °C
There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing. Second, liquid oxygen is a fire hazard; it creates an atmosphere of pure oxygen that allows substances to burn more easily. Nitrogen does not support combustion.
By fractional distillation. Allow liquid air to get less cold. At around 77.4K, nitrogen will boil off while oxygen will remain liquid. The temperature will begin to rise again when all the nitrogen has boiled off.
Nitrogen only remains a liquid at very low temperatures (-196oc) above this temperature the liquid will return to a gas, so warm it us is the answer, although because of the extreme cold temperatures and the asphyxiating nature of the gas it needs to done safely and only by trained personnel using the correct equipment.
No, as nitrogen on its own does not support combustion. Combustion is technically an oxidation process (reaction of a chemical with oxygen) and without oxygen, combustion of any fuel would be impossible to achieve.If you are suggesting using nitrogen as a fuel, that is not viable as well since nitrogen is not highly combustible (otherwise air which is 23% oxygen and 75% nitrogen would permanently be combusting).Nitrogen storage would also be a problem since to store nitrogen as liquid, very high pressures are needed and liquid nitrogen is very cold (-190 Degrees C)
Liquid nitrogen is made by taking in air from the atmosphere and compressing and cooling it. Once it is cool enough, it forms a liquid. This liquid contains argon, oxygen and nitrogen. These elements are then separated and sold as a commodity. The temperature is the only difference.
Yes, liquid nitrogen can become contaminated if it comes into contact with substances or materials that are not meant to be frozen or stored in liquid nitrogen. Contamination can affect the purity and properties of the liquid nitrogen, so it is important to handle and store it properly to prevent contamination.
Liquid nitrogen is simply nitrogen gas in its liquid state. The stuff is so cold you can consider it like an acid if you are ever stupid enough to stick your finger in there without cryogenic protection. By immersing them in liquid nitrogen you can turn marshmallows hard as bullets, shatter flowers like glass, turn a soft peach into something that can hammer nails into wood, and a whole lot of other things.

Yes, freeze air until it becomes a liquid and perform fractional distillation. Oxygen, nitrogen and other gases will be produced.
