Being the smaller molecular weight, the water molecules will move faster (transla. As alcohol evaporates at a much faster rate compared with water due to its lower boiling temperature (82 compared to 100 degrees C), it is able to carry away more heat from the skin. So, how long does it take for alcohol to evaporate completely? This means the hydrogen bonds holding the molecules together need to be broken. Where's my experimental error coming from? Increase the surface area by placing the water in a shallow tray. Which evaporates faster rubbing alcohol or water? It might help someone to give you a better answer. This is because it has a relatively low boiling point of 82.4 degrees Fahrenheit. And since vapor is less dense than liquid, it rises and dissipates more quickly. 26 Rubbing Alcohol Uses: Home Health, Household Cleaning, and More $$\overline{E_\text{k}}=\frac{3}{2}k_\text{B} T$$ A complete model includes consideration of the following: So, in principle, you could do it. This type of alcohol evaporates very quickly, in just a few minutes. As the vapor pressure increases. The evaporation rate is affected by the temperature, humidity and air flow. But just how fast does it evaporate? Clean the surface of the material. Besides that, hes a hobbyist blogger and research writer. Otherwise, you could certainly give this a try at home with a lower purity ethanol and see if you can extrapolate. This is based on an average evaporation rate of 0.3 ml/min/cm.

More to explore How fast does alcohol evaporate from vodka, Does alcohol evaporate at room temperature, The Five Biggest Sports Clubs In The World. After establishment of equilibrium (fast), the rate-determining step of the evaporation is probably the diffusion of the gaseous ethanol molecules away. If there is a residue, it is due to dissolved or suspended impurities, including anything it may have dissolved from the surface that it is evaporating on.Shah. As a general rule of thumb, you can expect isopropyl alcohol to evaporate completely in about 30-60 minutes. This residue can be cleaned up with water or another solvent.
