False

Front

Surface tension of the water is the cohesive force between water molecule on the surface of water.

Back

True

Front

Cohesive force between water molecules and adhesive force between water molecules and other molecules enable this phenomenon to occur. Options: surface tension, capillary action, float on water, photosynthesis.
