Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...
One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas. It is a paramagnetic , bent molecule with C 2v point group symmetry . Industrially, NO 2 is an intermediate in the synthesis of nitric acid , millions of tons of which are produced each year, primarily for the production of fertilizers .
Christ's side pierced by a lance, drawing blood. Blood of Christ, also known as the Most Precious Blood, in Christian theology refers to the physical blood actually shed by Jesus Christ primarily on the Cross, and the salvation which Christianity teaches was accomplished thereby, or the sacramental blood (wine) present in the Eucharist or Lord's Supper, which some Christian denominations ...
Liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in an insulating layer of nitrogen gas bubbles. This effect, known as the Leidenfrost effect , occurs when any liquid comes in contact with a surface which is significantly hotter than its boiling point.
Atmospheric constituents such as nitrogen oxides can be stratified vertically in the atmosphere. Ott noted that the lightning-produced NO x is typically found at altitudes greater than 5 km, while combustion and biogenic (soil) NO x are typically found near the sources at near surface elevation (where it can cause the most significant health ...
The composition of gases present in the soil's pores, referred to commonly as the soil atmosphere or atmosphere of the soil, is similar to that of the Earth's atmosphere. [5] Unlike the atmosphere, moreover, soil gas composition is less stagnant due to the various chemical and biological processes taking place in the soil. [5]
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
Forming gas is a mixture of hydrogen (mole fraction varies) [1] and nitrogen. It is sometimes called a "dissociated ammonia atmosphere" due to the reaction which generates it: 2 NH 3 → 3 H 2 + N 2. It can also be manufactured by thermal cracking of ammonia, in an ammonia cracker or forming gas generator. [2]
