Mar 19, 2024 · Ethanol, a commonly used alcohol, has a boiling point of approximately 78.4 degrees Celsius (173.12 degrees Fahrenheit) at standard atmospheric pressure. This means that ethanol will start to vaporize and turn into a gas at this temperature.
Sep 15, 2022 · Explain why the boiling points of alcohols are higher than those of ethers and alkanes of similar molar masses. Explain why alcohols and ethers of four or fewer carbon atoms are soluble in water while comparable alkanes are not soluble. Alcohols can be considered derivatives of water (H 2 O; also written as HOH).
For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 °C (173 °F), whereas propane (MW 44) has a boiling point of −42 °C (−44 °F). Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly than are propane molecules.
Nov 28, 2022 · Here is a look at the boiling point of different types of alcohol. The boiling point of ethanol or grain alcohol (C 2 H 5 OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C). Methanol (methyl alcohol, wood alcohol): 66°C or 151°F. Isopropyl Alcohol (isopropanol): 80.3°C or 177°F. Read More.

The curve between the critical point and the triple point shows the ethanol boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature. At the critical point there is no change of state when pressure is increased or if heat is added.
