Because of the relatively high forces of attraction among the water molecules due to intermolecular hydrogen bonding, water has $a$ higher surface tension than most other liquids.
Related Theory
Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons.
