What is produced on the top of a pool of water by the mutual attraction between water molecules?

-surfactant

-surface tension

-a much smaller volume

-a much higher density

Verified Answer :

Answer: surface tension

Explanation:

Surface tension is the net downward force acting on the surface of liquids due to the cohesive nature of liquids.

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom. Thus water molecules present on the surface are strongly attracted by the molecules present below the surface and thus act as a stretched membrane.

The surface acquires a minimum surface are and thus acquire a spherical shape.

Answer:

-surface tension

Explanation:

Surface tension is a term that applies to liquids since it is a way to measure the cohesion between the molecules of that liquid. All molecules that are composed of a liquid substance interact in some way with each other and attract. It is said that a liquid has more or less cohesion, depending on whether its molecules are more or less attracted to each other.


Surface tension is only applied to the surfaces of a liquid. When we are on the surface of a liquid, the molecules that are below the surface, feel that attraction only for the molecules that they have on the sides and down, but on the top there are no more molecules, only the surface. As a result of all this, these molecules feel a force that stretches them down, into the liquid.


The surface tension depends on the nature of each liquid. Surface tension is defined in physics as the amount of energy needed to increase the surface of a liquid and counteract that force of attraction inwards.
