The properties of a surface molecules are different from those of the bulk liquid because
\( \mathrm{P} \) the surface molecules :-

W
(i) are smaller than other molecules
(ii) acquire charge due to collision from air molecules
(iii) find different type of molecules in their range of influence
(iv) feel a net force in one direction
(1) (i), (ii)
(2) (ii), (iii)
(3) (iii), (iv)
(4) (i), (iv)
