Water has a high surface tension do to hydrogen bonding.
Water = less Viscosity
syrup = high Viscosity
EX: rubber, glass
The vapor pressure of the liquid = air pressure above the liquid
Note: The normal boiling point of water is 100oC. The term normal refers to standard pressure or 1 atm, or also 101.3 kPa.
Vapor Pressure: Pressure exerted by molecules that have enough energy to escape the surface.
As T ↑ VP↑evaporation ↑
Liquids with high VP are volatile (alcohol evaporates easily)
Liquids that have strong IMF have low vapor pressures.
(take a lot of energy to overcome IMF so it can evaporate)
