After a few minutes, the water begins to freeze. log10(P) = A – [B / (T + C)], where P is the calculated vapor pressure in bar (on an absolute scale) and T is the temperature in Kelvin. Vapor pressures of aqueous solutions of ethylene glycol are measured in the range of temperature from -10 to 60°C and concentration from 20 to 50wt%. NO open flames. A solution of ethylene glycol and water has a vapor pressure of 1.00 atm at 110 degrees celsius. You will have one unknown in the equation which is the mole fraction of ethylene glycol. Benzene (for example) has a higher vapour pressure which means it meets atmospheric pressure (the definition of boiling point) at a …
