The causes of this recent AMOC slow-down remain highly debated and may be related to natural decadal variability Zhao and Johns , ; Jackson et al. However, longer-term evidence, including sea surface temperature fingerprints and coral-based proxies, also suggest AMOC weakening — by about 0. Although climate models disagree on the precise magnitude of the AMOC weakening — and differ substantially in their representation of the strength and depth of the AMOC — model simulations predict AMOC weakening in response to increasing greenhouse gases Gregory et al. This has been related to reduced ocean heat loss, and secondarily through increased freshwater input at high latitudes, both of which decrease the density of sea water in the subpolar North Atlantic i. Warming of the tropical Indian Ocean — by means of atmospheric teleconnections and changes in ocean salinity and circulation — may exert a stabilizing effect on the AMOC, attenuating its recent weakening Hu and Fedorov , Overall, our understanding of how anthropogenic perturbations impact the AMOC remains limited. There is considerable debate on the role of anthropogenic aerosols in driving North Atlantic climate variability. One study argued anthropogenic aerosols are the dominant driver of Atlantic Multidecadal Variability a broad term encompassing Atlantic climate variability , primarily through aerosol—cloud interactions and modification of net surface shortwave radiation Booth et al.
Latent heat of vaporization nitrogen - assured, that
. latent heat of vaporization nitrogenIt forms an equilibrium mixture with nitrogen dioxide. The N-N distance corresponds to a weak bond, since it is significantly longer than the average N-N single bond length of 1. Inevitably, some dinitrogen tetroxide is a component of smog containing nitrogen dioxide.
Nitrogen – Latent Heat of Vaporization
Production[ edit ] Nitrogen tetroxide is made by the catalytic oxidation of ammonia : steam is used as a diluent to reduce the combustion vaporlzation. The gas is essentially pure nitrogen dioxide, which is condensed into dinitrogen tetroxide in a brine-cooled liquefier. This synthesis is more practical in a laboratory setting and is commonly latent heat of vaporization nitrogen as a demonstration or experiment in undergraduate chemistry labs. The oxidation of copper by nitric acid is a complex reaction forming various nitrogen oxides of varying stability which depends on the concentration vaporizatio the nitric acid, presence of oxygen, and other factors.
The unstable species further react to form nitrogen dioxide which is then purified and condensed to form dinitrogen tetroxide. Use as a rocket propellant[ edit ] Nitrogen tetroxide is used as an oxidizer learn more here one of the most important rocket propellants because it can be stored as a liquid at room temperature. In earlyresearch on the usability of dinitrogen tetroxide as an oxidizing agent for rocket fuel was conducted by German scientists, although the Germans only used it to a very limited extent as an additive for S-Stoff fuming nitric acid.

It is a hypergolic propellant in combination with a hydrazine -based rocket fuel. One of the earliest uses of this combination was on the Titan family of rockets used originally as ICBMs and then as launch vehicles for many spacecraft. Latent heat of vaporization nitrogen on the U. Gemini and Apollo spacecraft and coastwide readymix on the Space Shuttle, it continues to be used as station-keeping propellant on most geo-stationary satellites, and many deep-space probes.
It is also the primary oxidizer for Russia's Proton rocket. When used as a propellant, dinitrogen tetroxide is usually referred to simply as nitrogen tetroxide and the abbreviation NTO is extensively used.
Additionally, NTO is often used with the addition of a small percentage of nitric oxidewhich inhibits stress-corrosion cracking of titanium alloys, and in this form, propellant-grade NTO vaporizahion referred to as mixed oxides of nitrogen MON. This was due to a switch accidentally left in the wrong position, which allowed the altitude control thrusters to fire after the cabin fresh air intake was opened, allowing NTO fumes to enter the cabin. One crew member lost consciousness during descent.
Upon landing, the crew was hospitalized for five days for chemical-induced pneumonia and edema. This hot nitrogen dioxide is expanded through a turbine, cooling it and lowering the pressure, and then cooled further in a heat sink, causing it to recombine into nitrogen tetroxide at the original molecular weight. It is then much easier to compress to start the entire cycle again. Such dissociative gas Brayton cycles have the potential to considerably increase efficiencies of power conversion equipment. If metal nitrates are prepared from N2O4 in completely anhydrous conditions, a range of covalent metal nitrates can be vaporizatjon with many transition metals.
This is because there is a thermodynamic preference for the nitrate ion latent heat of vaporization nitrogen bond covalently with such metals rather than form an ionic structure. Such compounds laetnt be prepared in anhydrous conditions, since the nitrate ion is a much weaker ligand than water, and if water is present the simple hydrated nitrate will form. The anhydrous nitrates concerned are themselves covalent, and many, e.
Many of the anhydrous transition metal nitrates have striking colours. This branch of chemistry was developed by Cliff Addison and Norman Logan at the University of Nottingham in the UK during the s and s when highly efficient desiccants and dry boxes started to become available.]
Between us speaking, in my opinion, it is obvious. I will refrain from comments.
In it something is. I thank for the information.
What good topic
I apologise, but it not absolutely that is necessary for me. There are other variants?
