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
The boiling point of a substance, in this case alcohol, is the temperature at which it changes state from liquid to gas (evaporation) throughout the bulk of the liquid. At the boiling point molecules anywhere in the liquid may be vaporized. for alcohol the evaporation temperature is 79C.

12.1 Celsius or 53.78 Fahrenheit.
Leaving at room temperature will evaporate ethanol, but will also pull moisture from the air, progressively diluting it to a lower proof - which would then change the evaporation temperature as it becomes a higher water content.
Yes, Ethanol or other alcohols are often found in Aftershaves and perfumes. Its these alcohols that give that 'cooling' feeling when you apply them, as the alcohol starts to evaporate on contact with the skin (~38 c) Its flash point is 14c (lowest temperature at which it can vaporise at 25c/102kPa aka STP)
Yes, ethanol evaporates easily due to its low boiling point of 78.37 degrees Celsius. This makes it volatile and prone to evaporating at room temperature.

If you put ethanol and water together in a beaker which would evaporate first?
Ethanol would because it has a boiling point of 78.4 C where as water has one at 100 C.Through this process breweries and wineries can distill their liquors and find the percent off ethanol (alcohol) by volume.
If a water ethanol mixture is distilled which will be collected first?
Ethanol will vaporize at a lower temperature than water, so it will be collected first during the distillation process. Ethanol has a lower boiling point (78.37°C) compared to water (100°C), allowing it to evaporate and be collected before water.
How strong is ethanol's odor?
Ethanol has a strong, distinctive odor that can be easily detected even in small amounts. Its smell is often described as sharp, sweet, or slightly fruity, and it can be overwhelming when present in high concentrations.
What is the solvent of tincture of iodine?
The solvent of tincture of iodine is typically ethanol, which helps dissolve the iodine and make it easier to apply to the skin. Ethanol also helps the iodine evaporate quickly, leaving behind a thin layer that can penetrate the skin.
Why is water a better conductor than ethanol?
Water is a better conductor than ethanol because it contains ions that can move freely and carry electrical charges, while ethanol does not dissociate into ions as readily. This means that water can facilitate the flow of electricity more easily than ethanol.
What are the four liquids that can evaporate easily?
Water, ethanol, acetone, and gasoline are examples of liquids that evaporate easily due to their low boiling points.
Why does a few drops of ethanol poured on your arm feel very cold?
Ethanol is an alcohol-based liquid. Alcohols evaporate when warmed - the heat from your arm causes the ethanol to evaporate - taking the heat from your arm as it does, which makes your skin feel cold.
How do you separate ethanol from aqueous ethanol?
Ethanol can be separated from aqueous ethanol through a process called distillation. In distillation, the mixture is heated to evaporate the ethanol, which is then condensed back into liquid form. The condensed ethanol can then be collected as a separate product.
Does methylated spirit evaporate faster than water?
Yes, methylated spirit (ethanol) evaporates faster than water because it has a lower boiling point. Ethanol boils at 78.37°C, while water boils at 100°C. This means ethanol molecules have higher kinetic energy and can escape into the air more easily.
Why is cold ethanol used instead of room termperature ethanol?
Cold ethanol is used to precipitate nucleic acids because it helps to increase the solubility of DNA or RNA, allowing for more efficient isolation. Cooling the ethanol also helps to promote the aggregation and precipitation of nucleic acids, which can then be collected more easily.
Why does water evaporates the fastest?
The question is based on a lack of understanding of the process of evaporation. Water does not evaporate the fastest - ethanol, for example, will evaporate faster.
Does the ethanol evaporate faster than a water?
yes it evaporates faster than water.
Can ethanol be separated from sand and water?
Yes, ethanol can be separated from sand and water using distillation. Ethanol has a lower boiling point than water, so by heating the mixture, the ethanol will evaporate first and can be collected, leaving the sand and water behind.
If you put ethanol and water together in a beaker which would evaporate first?
Ethanol would because it has a boiling point of 78.4 C where as water has one at 100 C.Through this process breweries and wineries can distill their liquors and find the percent off ethanol (alcohol) by volume.
Why does surgical spirit evaporate faster than water?
The ethanol enthalpy of vaporization is lower compared to water.
Unlike other kinds of liquids volatile liguids?
Volatile liquids have a high vapor pressure and evaporate easily at room temperature. This is due to their low boiling points, which causes them to quickly turn into vapor. Examples of volatile liquids include ethanol and gasoline.
Is strontium bromide soluble in ethanol?
Yes, strontium bromide is soluble in ethanol. Ethanol is a polar solvent, and strontium bromide is an ionic compound, so it dissolves easily in polar solvents like ethanol.
