i think it's friction
It is surface tension.
Surface tension
Surface tension is the force that pulls liquids together to form drops when they fall. This force is due to the cohesive forces between the liquid molecules at the surface.
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
It is surface tension.
Surface tension.
Surface tension is the force that acts on particles at a liquid's surface. It is caused by the cohesive forces between the liquid molecules, which creates a barrier that resists the penetration of external objects or forces. This force is responsible for phenomena such as capillary action and the formation of droplets.
Because of surface tension
surface tension
Some insects can stand right on the surface tension of the water.
The pull on the surface of liquids that allow liquids to form drops when they fall are called surface tension. This property is due to the cohesive forces between liquid molecules at the surface.
Substance tension refers to the force that holds particles together in a substance. It is responsible for the surface tension of liquids, such as water, which causes them to form droplets and create a "skin" on the surface.
