Does isopropyl alcohol evaporate quickly?
The molecules of isopropyl alcohol don't stick together as strongly at room temperature as water molecules do, which means the alcohol evaporates more quickly than water does. More molecules fly off, and they carry more heat energy with them.
Does isopropyl completely evaporate?
Pure isopropyl alcohol would normally evaporate completely at room temperature in our standard atmosphere. 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.
How long does it take alcohol to evaporate at room temperature?
