Manufacturing Processes Monsoon said: What are you trying to accomplish or is it just a random question? Hoffman Estates Cheap Room. Cbd Boiling Point Under Vacuum . When the ambient pressure is as low as that of vacuum, the boiling point of the substance reduces. In vaccum the boiling point of Ethanol reduces because the ambient pressure decreases. Whenever a liquid is heated, and this pressure balance takes place, it turns into vapor. Methanol Boiling Point. The boiling point of water is the temperature at which the vapor pressure of the liquid water equals the pressure surrounding the water and the water changes into a vapor. From this, a greater amount of hydrogen bonding can take place between water molecules than between methanol molecules. A recipe had to be baked 2 hours or longer to bring the alcohol content down to 10percent or lower.
