The drop of acetone evaporates much faster than the ethanol which evaporates faster than the drop of water. Physicists Surprised to Find That Thick Fluids Like Honey Flow Faster No additional source of energy is required for evaporation, and the water does not need to reach the boiling point to evaporate. The seven steps in the water cycle are:1. Mike W. (published on 06/26/2010) Take appropriate precautions. Putting a happy aqueous bacterium into 100% glycerol will cause immense osmotic shock, probably resulting in death for most bacteria, due to too much of their intracellular water trying to escape to the extracellular, water-free (but glycerol rich) environment. Step 2: Evaporation of rubbing alcohol. Its melting point is 18 C (64.4 F), and its boiling point is 290 C (554 F).
