2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [1] [2] As a refrigerant, it is designated R-1234yf [1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [3]
2 and 20 percent oxygen O 2. Both molecules are small and non-polar (and therefore non-associating). We can therefore expect that the behaviour of air within broad temperature and pressure ranges can be approximated as an ideal gas with reasonable accuracy. Experimental values for the compressibility factor confirm this.
An air mass originating over northern Siberia in winter may be indicated as "cA". [3] The stability of an air mass may be shown using a third letter, either "k" (air mass colder than the surface below it) or "w" (air mass warmer than the surface below it). [3] An example of this might be a polar air mass blowing over the Gulf Stream, denoted as ...
The West Papua National Liberation Army (Indonesian: Tentara Pembebasan Nasional Papua Barat; abbreviated as TPNPB), officially referred to in Indonesia as the Armed Criminal Group (Indonesian: Kelompok Kriminal Bersenjata, [1] abbreviated as KKB), and after 2021, Separatist Terrorist Group (Indonesian: Kelompok Separatis Teroris, abbreviated as KST [2]), is a Western New Guinean insurgent ...
2 (736 J⋅K −1 ⋅kg −1) is greater than that of an hypothetical monatomic gas with the same molecular mass 28 (445 J⋅K −1 ⋅kg −1), by a factor of 5 / 3 . The vibrational and electronic degrees of freedom do not contribute significantly to the heat capacity in this case, due to the relatively large energy level gaps for both ...
The types of Mutlaq water are as follows: [8] Kurr water: is a certain quantity of Mutlaq water (480 kg) that does not become Najis (impure) if it comes in contact with Najis things, also Kurr water can purge Najis things.
