2. Liquid nitrogen is one of the coldest Substance on Earth

Liquid nitrogen is arguably one of the coldest substances on earth with a boiling point of -195.8 degrees Celsius. Due to its nature, it can lead to severe cold burns when not handled with care. Sometimes it can cause frostbite when it comes in contact with the skin. When liquid nitrogen is placed on a surface or an object, it rapidly evaporated due to the increase in temperature. The rapid evaporation leads to a drop in the temperature within the surrounding. If the skin is exposed to this extremely cold liquid, it causes a freeze of the skin tissue, which subsequently leads to frostbite.

Nitrogen is a critical element that has a significant impact on sustaining life. However, it can be equally severe to humans if not handled with caution. In its gas state, it is not harmful but in its liquid state, it can be very harmful. When carelessly handled and comes in contact with the skin, it causes the skin to freeze due to the cold temperatures and this may cause frostbite. It is, therefore, necessary that nitrogen liquid is handled with care and by professionals.

4. Nitrogen is used in the Manufacture of Nitric Acid

Nitrogen has proven to be not only a gas that is abundant in space but an important material in the production of several materials. Nitrogen is used in the production of nitric acid which is also used in the production of other materials such as fertilizers, dyes, explosives, and other materials. It forms the basis of the production of a variety of materials that are essential in the life of human beings. However, it is important to note that these chemicals can be corrosive and require precautions and safety measures while handling.

5. Nitrogen is utilized by plants through a process of Nitrogen Fixation

Nitrogen fixation is the process by which free nitrogen in the space is converted into ammonia which is assimilated by plants by the use of bacteria such as Rhizobium and Azotobacter. These bacteria convert nitrogen into a form that enables the plants to use through the root system. This process is important in enhancing the biological processes of the plant which include excretion, transportation, growth, and absorption.

6. It plays a significant role in Food Preservation

Nitrogen plays a significant role in the food industry, especially in the preservation of food. One of its important characteristics in food preservation is its ability to provide an uncreative atmosphere where bacterial activity cannot take place. Nitrogen is used in the commercial production and preservation of bulk foods through packaging.

7. Nitrogen is an essential element for the Growth and Development of Plants

Nitrogen plays a significant role in plant growth and development. It is an important ingredient in chlorophyll which is vital for the photosynthesis process. Photosynthesis is simply the process by which plants convert water, carbon dioxide, and sunlight into water, sugar, and oxygen. The plants use converted sugars for their growth and development. Nitrogen in this case plays a critical role in the synthesis of chlorophyll.

8. Nitrogen is a major element in many Organic Compounds

Nitrogen is a critical component in several organic compounds such as proteins, nucleic acids, and amino acids among others. Organic compounds an essential for life and nitrogen being one of the key elements plays a significant role in their functions and structure. In proteins, nitrogen is used in peptide bonds where amino acid bonds are connected with the nitrogen atoms to form the protein chain. The presence of nitrogen in these molecules is critical in defining the cellular structure and other biological processes.

9. It is Odorless, Tasteless, and Colorless

Nitrogen gas exhibit characteristics that include odorless, tasteless, and colorless. Nitrogen gas is odorless and therefore lacks any scent and goes unnoticed in our body system. It is also colorless and no matter how much we look into the space we cannot identify elements of nitrogen gas. It is also tasteless meaning it does not affect the taste of anything that we consume. However, despite being tasteless, odorless, and colorless it remains a vital component in our space for various biological and environmental processes that affect our existence on Earth.

10. Nitrogen is a crucial component in the Nitrogen Cycle

The nitrogen cycle is the circulation of nitrogen in the atmosphere to strike a balance through the earth’s ecosystem. The cycle is important in sustaining life in general. It is the process that helps maintain the balance of nitrogen in the atmosphere. The nitrogen cycle is critical in sustaining the life of plants and animals as it plays a significant role in the growth and development of plants. On the other hand, plant sustains the animals with food, and the food chain is maintained. 

11. Nitrogen was discovered by Daniel Rutherford in 1772

Nitrogen was discovered in 1771 by a Scottish physician known as Daniel Rutherford. Daniel conducted an experiment where he confined space and used an absorption process to absorb oxygen and carbon dioxide. After removing oxygen and carbon dioxide from space he realized there was still a significant percentage of are that remained in the confined space. He referred to the remaining gas as “noxious air” which later came to be known as nitrogen gas. His experiment led to the realization that the atmosphere is composed of several gases. His experiment laid a foundation for other scientists to research and gets to know more about the gases in our surrounding.

12. Lightning can cause Nitrogen and Oxygen to combine to make Acid Rain
