What is the corresponding temperature in the Fahrenheit scale? C) the temperature on the Kelvin scale corresponding to 32F. Why is H2O a liquid and H2S a gas? Nitrogen is used to chill, freeze or control temperature of food products. Liquid Nitrogen Boiling Point. H2O is a liquid at room temperture because it is highly associated via intermolecular hydrogen bonding. 77.2 k is -195.95 C. To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. This heat flow will result in the evaporation of liquid nitrogen. 10) The temperature of liquid nitrogen is-196 C. scale? Liquid nitrogen at standard atmospheric pressure (14.7PSI) boils at 77Kelvin, this is -196 Celsius or -321 Fahrenheit. Liquid nitrogen (LN) is an inert cryogenic fluid with a temperature of − 196 °C [− 320 °F]. So why is nitrogen a liquid while carbon dioxide is a solid? Because liquid nitrogen in a usual setting is boiling, its usual temperature is 77 K. Chemical, physical and thermal properties of Nitrogen: Values at 25 o C (77 o F, 298 K) and atmospheric pressure. These tanks have plumbing to transfer either gas and/or liquid nitrogen via insulated steel hoses. Nitrogen is inert except when heated to very high temperatures, where it combines with some of the more active metals, such as lithium and magnesium, to form nitrides. Lower limit for calculation: -210 C, 0.13 bar bar upper limit: -148 C, 33 bar. The boiling point of nitrogen is -195.8 degrees Celsius [77.4K].
