Solution: Surface tension arises because a) The thermodynamic standard state conditions prevent the molecules at the top of the liquid from moving around easily so that they form a "skin" and a bug can walk on it b) Intermolecular forces are stronger at the surface of a liquid than in the bulk of the liquid. c) The suspension of a homogeneous mixture of molecules creates resistance to spreading out of the liquid, thereby increasing its surface area. d) A representation showing specific connections between atoms in a molecule is stronger at the surface from elementary thermodynamics. e) The dissociation of the substance, useful in interpreting colligative properties, is stronger at the surface of a liquid, which prevents the molecules from breaking down so that a bug can walk on it.

Problem

Surface tension arises because

a) The thermodynamic standard state conditions prevent the molecules at the top of the liquid from moving around easily so that they form a "skin" and a bug can walk on it

b) Intermolecular forces are stronger at the surface of a liquid than in the bulk of the liquid.

c) The suspension of a homogeneous mixture of molecules creates resistance to spreading out of the liquid, thereby increasing its surface area.

d) A representation showing specific connections between atoms in a molecule is stronger at the surface from elementary thermodynamics.

e) The dissociation of the substance, useful in interpreting colligative properties, is stronger at the surface of a liquid, which prevents the molecules from breaking down so that a bug can walk on it.
