This is because the molecules with the highest kinetic energy are lost to evaporation (see the video on evaporative cooling for more info). But before we dive into its cooking applications in too much depth, let's first go over the basics of what evaporation is. The three -OH groups in glycerol are polarised and this helps them to easily dissolve in water. It does evaporate but very slowly. The raindrops and snowflakes fall to the ground and turn into water.7. To burst a cell, you need water to flow in, so you need water that is not salty. Methanol, CH3OH, is the simplest, containing only one carbon atom. This pressure alters the effective pumping rate. The OH group can reasonably be viewed as two thirds of a water molecule (H2O, or HOH), and this is responsible for the physical and chemical properties of the alcohols. Why is glycerine more viscous than water? It is equal to atmospheric pressure at 100C, the boiling point. Soap that contains glycerol absorbs moisture from humid air. Step 2: Take a dime-sized .
