Evaporation is a process that: ((MCAER 2014))

✅Explanation: Cryopreservation is the process of preserving biological materials at extremely low temperatures. Liquid nitrogen, with its boiling point of -196 degrees Celsius, is ideal for this purpose as it can rapidly cool and preserve biological samples.

🔑Key Points:
-Liquid nitrogen has many uses, mainly based on its cold temperature and low reactivity.
-Examples of common applications include
-The freezing and preservation of food products
-The preservation of biological samples, such as sperm, eggs, and animal genetic sample. 
-Used as a coolant for superconductors, vacuum pumps, and other materials and equipment.
-Used cryotherapy to remove skin abnormalities.
-The shielding of materials from the oxygen exposure
-The quick freezing of water or pipe allow work on them when valves aren't available
-A source of extremely dry nitrogen gas.

🛑Additional Information:
-Liquid helium
-It is a physical state of helium, at very low temperatures if it is at standard atmospheric pressures. Liquid helium may show superfluidity.
-Owing to its low melting point, liquid helium has numerous applications in cryogenics, magnetic resonance imaging (MRI), and superconducting magnets.
-Liquid argon
-It is tasteless, colourless, odourless, noncorrosive, nonflammable, and extremely cold. Belonging to the family of rare gases, argon is the most plentiful, making up approximately 1% of the earth’s atmosphere.
-It is monatomic and extremely inert, forming no known chemical compounds.
-Argon is most commonly used in its gaseous state.
-It is widely used in the lighting industry for filling bulbs and with combinations of other rare gases for the filling of special bulbs and tubes for special colour effects.
-The welding industry uses argon as a shielding gas to protect the metal from oxidation during welding. Argon is also used extensively in the semiconductor manufacturing process as a purge gas.
-Bromine
-It is a chemical element with the symbol Br and atomic number 35.
-It is the third-lightest halogen and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
-Its properties are intermediate between those of chlorine and iodine.
