FTP, name this property of liquids, used to explain why they form droplets.
In one phase of matter it can be thought of as work required to remove an area of an outer layer or as force acting on that area to minimize its extent.  In the former case, it has the unit of energy per area, and in the latter case the equivalent unit of force per length.  Arising primarily from London and dispersion forces, its high value in some liquids, such as water, is because of hydrogen bonding.
