Vor 4 Tagen · List of gases. Boiling liquid oxygen. This is a list of gases at standard conditions, which means substances that boil or sublime at or below 25 °C (77 °F) and 1 atm pressure and are reasonably stable.
Vor 3 Tagen · With a boiling point near 85 °C (185 °F) (n-octane boils at 125.62 °C (258.12 °F)), it was well-suited for early carburetors (evaporators). The development of a "spray nozzle" carburetor enabled the use of less volatile fuels.
Vor 21 Stunden · Zink ist auf der Erde mit einem Gehalt von 0,0076 % (oder 76 ppm [6]) an der Erdkruste ein relativ häufiges Element. Wenn man die Elemente nach Häufigkeit ordnet, steht es damit an 24. Stelle. [6] Es ist häufiger als Kupfer oder Blei . Überwiegend findet sich Zink gebunden in Erzen.
Vor 5 Tagen · \(BP\) is the boiling point in Fahrenheit, \(P\) is the atmospheric pressure in inches of mercury (inHg), \(\ln\) denotes the natural logarithm. Example Calculation. At an atmospheric pressure of 29.92 inHg (standard atmospheric pressure at sea level), the boiling point of water is approximately:
Vor 4 Tagen · That is why acetic acid’s boiling point (1 1 8 ∘ C) is much higher than ethanol’s boiling point (7 8 ∘ C). The boiling point of any one carboxylic acid molecule depends on its size. Large carboxylic acid molecules tend to have high boiling points because they are long and they generate relatively strong London dispersion forces.
Vor einem Tag · Esters tend to have lower boiling points than alcohols and carboxylic acids as hydrogen bonds cannot form between ester molecules. Esters are volatile and are largely insoluble. Esters tend to be sweet smelling; thus, they are used as flavorings and in perfumes. They are also used as industrial solvents, used to make up vegetable and ...
