Question

Surface tension is an atomic/molecular
property of
(a) atoms in the interior
(b) atoms at surface
(c) atoms which are exterior
(d) atoms at surface bounded entirely by
different atoms​

Answer 1

Answer:

atoms at surface bounded by entirely by diffrent atoms.

Answer 2

Answer:

Surface tension is an atomic/molecular property of atoms at the surface bounded entirely by different atoms​ i.e.(d).

Explanation:

Surface tension is described as the energy or tension produced by liquid molecules as a result of their cohesion in order to resist external forces and reduce surface area.

Let's analyze the options one by one,

(a)Atoms in the interior-This option is incorrect since the inside atoms do not experience any force because it is neutralized by the surrounding atoms.

(b) atoms at the surface- This option is incorrect since surface tension is an atomic/molecular property of atoms at a surface that is totally delimited by different atoms.

(c) atoms which are exterior-This option is incorrect since surface tension is an atomic/molecular property of atoms at a surface that is completely delimited by different atoms.

(d) atoms at the surface bounded entirely by different atoms​-Thus Atoms at the surface bounded entirely by different atoms either air or other matter, will exert a net inward force which is the cause that molecules tend to contract and the surface is under tension which is basically known as surface tension. This option is correct.
