R For Nitrogen. Liquid nitrogen is very cold and and contact may cause frostbite Under prolonged exposure to fire or heat nitrogen containers may rupture violently and rocket The phase diagram of nitrogen is shown below the table Chemical physical and thermal properties of Nitrogen Values at 25 o C (77 o F 298 K) and atmospheric pressure Molecular Weight Molecular Weight 28013Specific Heat Ratio cp/cv 140Specific Gravity air = 1 0967Specific Volume ( ft3/lb m3/kg) 1398 0872.

The Individual Gas Constant RThe Universal Gas Constant RuThe Molecular Weight of A Gas MixtureThe Universal Gas Constant Ru in Alternative UnitsThe Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas The value is independent of temperature The induvidual gas constant R for a gas can be calculated from the universal gas constant Ru (given in several units below) and the gas molecular weight Mgas R = Ru/Mgas In the imperial system the most common units for the individual gas constant are ft lb/slug oR In the SI system the most common units are J/kg K Unit conversion 1 J/kg K = 597994 ft lb/slug °R and 1 ft lb/slug °R = 0167226 J/kg K The Individual Gas Constant for gases For full table rotate the screen! The Universal Gas Constant Ru appears in the ideal gas law and can be expressed as the product between the Individual Gas Constant R for the particular gas and the Molecular Weight Mgas for the gas and is the same for all ideal or perfect gases The average molecular weight of a gas mixture is equal to the sum of the mole fractions of each gas multiplied by the molecular weight of that particular gas atmcm3/(molK) 82057338atmft3/(lbmolK) 131443atmft3/(lbmoloR) 073024atml/(molK) 0082057338.

Nitrogen (N) is an essential element of life and a part of all plant and animal proteins Nitrogen can be produced in several ways Some plants such as soybeans and other legumes recover nitrogen directly from the atmosphere or from the soil in a process know as “fixation” whereby the plant converts nitrogen into carbohydrates essential amino acids and proteins Molecular Formula N2PubChem CID 947.
