Liquid nitrogen, at a chilling -196 degrees Celsius, is widely used for cryopreserving biological samples and extending the shelf life of food and medical supplies. In food processing, it’s employed for rapid freezing, enhancing textures like in ice cream production. This versatile substance also plays a critical role in medical, scientific experiments, and industrial applications by providing ultra-low temperatures. Overall, liquid nitrogen serves as a vital tool for cooling and freezing in various fields.
