Answer:
Hydrogen bonds provide higher surface tension to a liquid. If you disrupt hydrogen bonds, surface tension will decrease. That's why at high temperature, surface tension is lower due to disruption of hydrogen bonds. Hydrogen bonds can be disrupted by the addition of surfactants and surface tension can be reduced also. Detergent is a surfactant because it interferes with the attractive forces between the water molecules.
