Can liquid nitrogen be used for cooling water?
Yes, liquid nitrogen can be used to cool water. When added to water, liquid nitrogen evaporates rapidly, absorbing heat from the water and lowering its temperature. It is commonly used in laboratories and industrial settings for this purpose.
When a gas cool and condenses becomes a?

What is the difference between nitrogen in the atmosphere and liquid nitrogen?
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.
What state is nitrogen at -300C?
It is not possible to cool nitrogen to −300 °C Nitrogen is a liquid at −196 °C
Can you use liquid nitrogen to cool your drinks?
You can but its a very costly affair. you can use ice instead or ordinary freezer to cool your drinks
Does liquid nitrogen Sublimate?
Liquid nitrogen is not dry ice. Dry ice is a solid form of carbon dioxide and liquid nitrogen is pure nitrogen in liquid form. Dry ice is frozen nitrogen. Liquid nitrogen is also frozen nitrogen, but is also pressurized. That's why it's in large, steel boxes. Chur.
Can liquid nitrogen be used for cooling your house?
Yes, liquid nitrogen can be used to cool air passed through a heat exchanger. It is however a once through system. You would need a tank to hold the liquid nitrogen, and have more delivered every so often. very expensive.
What are the two methods to cool down substances?
- place a sample in a refrigerator- place a sample in liquid nitrogen
Is liquid nitrogen boiling in a refrigerator a physical or chemical change?
It is a physical change, a change in phase from liquid to gas (evaporation). The nitrogen is chemically the same at the lower liquid temperature, but has some different properties because of its ability to absorb heat. If you cool the nitrogen gas , it will turn liquid again.
Can the use of liquid nitrogen on your skin cause an allergic rash?
No. Nitrogen does not irritate skin. But liquid nitrogen is extremely cold, and it can damage and kill skin (and other) tissue. It is a bad idea to allow your skin to come into contact with liquid nitrogen. Note: Some warts are "frozen" in an effort to remove them. In a clinical setting, liquid nitrogen is sometimes used to super-cool an instrument so the wart can be frozen. But this is a medical procedure and is done by professionals. Liquid nitrogen is not something that should be looked upon as a "toy" or "recreational plaything" by anyone.
Is there a more common coolant besides liquid nitrogen to cool below 75K?
Helium is used but it is more expensive.
Could a country like Iran use liquid nitrogen for weapons purposes?
Perhaps in a roundabout way. Gas centrifuges need to be cooled as they are spun to separate different isotopes of uranium from one another, and liquid nitrogen could be used to cool the centrifuges. But we track other things to determine whether or not Iran or another country is making weapons, particularly if they are weapons of mass destruction.
