Glycerol behaves similarly on skinit does not evaporate and it retains moisture. One could argue that glass is a very slow-moving, viscous liquid (although it has lots of properties of a solid, like rigidity). 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.

Absolute (dynamic) viscosity values for some common fluids. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The part of the ice cube in the water melts faster than the ice in the air, but as the ice cube melts, it sinks further down. Also unusual compared to other alcohol compounds is that glycerin has a relatively high boiling point. To burst a cell, you need water to flow in, so you need water that is not salty.

Water-based lubricants come in two general types, with and without glycerin. Glycerol has three hydrogen bonds which results in an extensive hydrogen bonding. Boiling water is a subset of vaporization of water, wherein the heating of the water is fast enough that vaporization is forced to occur very rapidly AND there is enough water such that the vaporization occurs under water. I need it for my science project, which is due TOMORROW, so if you could answer as soon as possible, that would be fantastic! The fastest? This is because the molecules with the highest kinetic energy are lost to evaporation (see the video on evaporative cooling for more info).
