What is the boiling point of Ethanol?
The boiling point of ethanol is 78.37 °C, 352 K, and 173 °F at 1 atmosphere pressure.
It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
The boiling point of ethanol is 78.4 degrees celcius at 1.0 atm. (760mmHg) pressure There is not one boiling temperature, because it depends on the overlaid gas pressure (normally air, but that is not important). The given boiling POINT is a temperature at a certain pressure, this is just one POINT of the (so called) p,T-line of all pressures and temperatures possible for boiling ethanol
What will be the boiling point of ethanol at 650 mm Hg when the normal boiling point at 760 mm Hg is 78.3 Celsius?
In order to bring ethanol to a boiling point while keeping the temperature at 35 degrees what would the pressure need to be reduced to?
The exact pressure would vary dependant on if you are referring to the boiling point of an ethanol azeotrope or absolute ethanol. For example the boiling point at 1 ATM for azeotropic ethanol is 78.15C and for absolute ethanol it is 78.4C. At a temperature of 35.0C azeotropic ethanol will boil in a vacuume pressure of 159.8 mbar/hPa or 119.9 mmHg/Torr where as absolute ethanol boils at a slightly lower pressure of 158.6 mbar/hPa or…
It isn't; their boiling points are (ethanol) 78.4oC and (Propanol) 97.1oC. The boiling point of propanol is greater because it is the third member in the series (with 3 carbon atoms) and ethanol is the second (with 2 carbon atoms). While they have similar bonding characteristics, propanol is simply heavier.
No. For example, ethanol (CH3CH2OH) and dimethyl ether (CH3OCH3) are structural isomers but have different boiling points. (The boiling point of ethanol is much higher than the boiling point of dimethyl ether because ethanol molecules can form hydrogen bonds with each other while dimethyl ether molecules cannot.)
It's not technically speaking, a vapour. But it is a volatile liquid (It readily evaporates). Boiling point is to do with the interactions between the molecules in a liquid. The stronger the interaction, the more energy is required to pull them apart. So the energy (heat) supplied at it's boiling boiling point is sufficient to break the interactions in ethanol. The boiling point of ethanol is 78.1 °C.
The relative ability of Ethane to boil depends upon the material it is compared too... Compared to Helium, it's boiling point is relatively high. Assuming you are comparing to a similar material such as ethanol... The reason why it has a low boiling point in comparison to ethanol is because ethanol has a hydroxy/alcohol group which can for hydrogen bonds. The only intermolecular force existing between ethane is dispersion forces (the weakest type of force)…
