As a subject matter expert in the field of cryogenics, I'm often asked about the coldest liquid possible. The answer to this question is quite fascinating and involves delving into the realm of low-temperature physics and chemistry. The coldest liquid we can produce and handle in a laboratory setting is liquid helium. Helium is unique due to its very low boiling point, which is at 4.2 Kelvin (-268.95 degrees Celsius). This makes it the coldest liquid that is stable under normal atmospheric pressure.
Liquid helium is not only the coldest liquid but also has a number of remarkable properties. For instance, it exhibits superfluidity at extremely low temperatures, which is a state where it flows without any resistance. This property has been extensively studied and is of great interest in various scientific fields, including quantum mechanics and material science.
However, the practicality of using liquid helium is limited by its scarcity and cost. Helium, while the second most abundant element in the universe, is not as readily available on Earth. This is due to the fact that it is a light gas that escapes Earth's atmosphere easily, making it difficult to collect and store. As a result, it is often reserved for applications where its unique properties are absolutely necessary.
In contrast, liquid nitrogen is a much more accessible and cost-effective alternative. It has a boiling point of -195.8 degrees Celsius, which is warmer than liquid helium but still extremely cold. Nitrogen is also the most abundant element in the Earth's atmosphere, making it much easier and cheaper to produce. This is why it is commonly used in various industrial and scientific applications, including as a coolant and in cryogenic freezing.
The use of liquid nitrogen allows us to save an enormous amount of energy and money. It is a lot cheaper than helium, and that is why we often use it for demonstrations and applications where the extreme cold of liquid helium is not required. The practicality and cost-effectiveness of liquid nitrogen make it a preferred choice in many situations.
Now, let's move on to the translation of the response.

It allows us to save enormous amount of energy and money. Liquid nitrogen is a LOT cheaper than the helium so we use that for our demonstrations. Even though Helium is the second most common element in the universe there is only a fixed amount available on the earth, so we don't waste any of it.
