Question
The surface tension of water on adding detergent to it
–Solution
In the solid and liquid phase, water molecules are bonded to each other by virtue of an interaction between hydrogen atoms on one molecule and the oxygen atom of another the process is referred to as "hydrogen bonding." The result is a kind of "skin" on liquid water's surface.
