∙ 10y agodepends on the percent solution.
here is an equation for a 50% wt solution i believe
enthalpy = -5E-06tx^3 + 0.0033tx^2 + 3.1782tx + 0.0492

∙ 12y agoEthylene glycol has a higher boiling point and a lower vapour pressure than water.

Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
59.0 KJ/mol
The theoretical reasons for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is because they are wetting agents.
You could determine its boiling point. The boiling point of ethylene glycol is 197.3 oC, and the boiling point of propylene glycol is 188.2 oC.
The boiling point of the mixture is higher than the boiling point of pure water; this slows down the evaporation of the coolant.
Ethylene glycol has a higher boiling point and a lower vapour pressure than water.
Density is just weight per unit volume, e.g. 1kg per liter. So just determine the weight and volume of your mixture.
The original mixture contains 41.4 ounces of glycol. for this to be 30 percent of the mixture, the total mixture must be 138 ounces, so 46 ounces of water must be added.

Water can be distilled from the mixture.
Raises the boiling point and lowers the freezing point.
The mixture of the two liquids (water and antifreeze ethylene glycol))has a higher boiling point and lower freezing point than water alone.
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
The chemical reaction with the mixture lowers the boiling point. The additives help with corrosion and the system moving parts wear.
Ethylene glycol and hexane is not a homogeneous mixture. This is because hexane cannot interact with ethylene glycol due to lack of dipoles.
