What makes a liquid a liquid is not a single defining trait but a convergence of physical properties that govern its response to forces, its energy state, and its molecular architecture. In a solid, molecules vibrate around fixed lattice points, held in place by strong bonds.
Understanding Intermolecular Forces in Liquids
The persistent, though transient, attraction between molecules is what gives a liquid its surface tension and allows it to maintain cohesion as it flows. In a gas, the kinetic energy is so high that it completely overcomes these attractions, allowing molecules to move independently.
However, because these molecules possess enough kinetic energy to overcome the majority of their mutual attractions, they can slide past one another. Dipole-Dipole Interactions: Occur between polar molecules, aligning partial charges to create moderate attraction.

London Dispersion Forces: Found in all molecules, these weak attractions become significant in larger atoms and non-polar liquids like oils. However, molecules at the surface lack neighbors above them, creating an imbalance that pulls them inward.
