why is nitrogen in air important for us? where do we use liquid nitrogen?
Answers
Answer:
LIN is an effective and convenient refrigerant due to its availability, low cost, and inert properties. It is also a practical cryogen for most low-temperature applications because of its extremely low boiling temperature at around −195.8°C as well as it high refrigeration capacity under atmospheric pressure
Explanation:
Nitrogen (N) is one of the building blocks of life: it isessential for all plants and animals to survive.Nitrogen (N2) makes up almost 80% of our atmosphere, but it is an unreactive form that is not accessible to us. ... Major sources of this reactivenitrogen include agriculture and the burning of fossil fuels.
Liquid nitrogen, which has a boiling point of -196C, is used for a variety of things, such as a coolant for computers, in medicine to remove unwanted skin, warts and pre-cancerous cells, and in cryogenics, where scientists study the effect of very cold temperatures on materials.
