Question

Which best explains the surface tension of water? •capillary action, •Cohesion, •Adhesion, •Sublimation?

Answer 1

hey Newbie

Answer 2

Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water. It allows small objects, even metal ones such as needles, razor blades, or foil fragments, to float on the surface of water, and it is the cause of capillary action. An everyday observation of surface tension is the formation of water droplets on various surfaces, or raindrop formation.

Answer 3

The physical and chemical behavior of liquids cannot be understood without taking surface tension into account. It governs the shape that small masses of liquid can assume and the degree of contact a liquid can make with another substance.

Answer 4

Surface tension is caused by the attraction between the liquid's molecules by various intermolecular forces. In the bulk of the liquid, each molecule is pulled equally in all directions by neighbouring liquid molecules, resulting in a net force of zero. At the surface of the liquid, the molecules are pulled inwards by other molecules deeper inside the liquid and are not attracted as intensely by the molecules in the neighbouring medium (be it vacuum, air or another liquid).

Answer 5

Therefore, all of the molecules at the surface are subject to an inward force of molecular attraction which is balanced only by the liquid's resistance to compression, meaning there is no net inward force. However, there is a driving force to diminish the surface area, and in this respect a liquid surface resembles a stretched elastic membrane. Thus the liquid squeezes itself together until it has the locally lowest surface area possible.

Answer 6

but thats a kinda long answer

Answer 7

@xhaileyxraine u got it ?

Answer 8

Cohesive attraction or cohesive force is the action or property of molecules sticking together, being mutually attractive. It allows for surface tension. This is the reason why water droplets have spherical shape, since they try to minimize the surface tension.

Answer 10

You probably didn't notice, but you posted your \(\large\sf\color{blue}{\underline{\href{ /study#/groups/Physics }{Physics }}}\) question in the Biology section.
Next time when you ask a question, check if you're in the right section :)

Answer 11

It is due to the inter-molecular forces of hydrogen bonding, which are not true bonds. AKA, cohesion.
Sublimation is when a solid goes to a gaseous state without a liquid state. This is why during really cold times in winter the ice on the ground sometimes disappears w/o melting.

Adhesion is similar to cohesion, but refers to one substance sticking to another.

capillary action is what moves water against gravity. This is why water gets higher and higher on jeans. Basically cohesion and adhesion in a thin tube cause the water (or other liquids) to move against gravity.

Answer 12

Cohesion
