Question: The physical properties of liquids is determined by
Options:
1) the disruptive motions of particles in a liquid only.
2) the attractions among the particles only.
3) the interplay between the disruptive motions of particles in a liquid and the attractions among the particles.
4) either the disruptive motions of particles in a liquid or the attractions among the particles.

Option 1: 'the disruptive motions of particles in a liquid only.' This ignores the cohesive forces that hold liquid molecules together and contribute to properties like surface tension, so it is incomplete.
Option 2: 'the attractions among the particles only.' While intermolecular forces are crucial, this view neglects how particle movement and kinetic energy (disruptive motions) compete with attractions to shape properties like viscosity and flow.
Option 3: 'the interplay between the disruptive motions of particles in a liquid and the attractions among the particles.' This captures the balance: thermal motion tends to separate particles and disrupt order, while intermolecular attractions resist separation, together determining properties such as boiling point, surface tension, viscosity, and density. It reflects the dynamic equilibrium that defines liquid behavior.
Option 4: 'either the disruptive motions of particles in a liquid or the attractions among the particles.' Suggesting that only one or the other governs properties is misleading because both factors operate simultaneously and their relative strengths set the observed properties.

In sum, the physical properties of liquids arise from a combination of kinetic (disruptive) energy and cohesive (attractive) forces, i.e., the interplay between them, rather than solely one of them or an either/or scenario.
