In liquids, particles oscillate around the equilibrium position, colliding with neighboring particles.

In liquids, particles oscillate around the equilibrium position, colliding with neighboring particles. From time to time, a particle makes a “jump” to a different equilibrium position. What property of liquids can be explained by this nature of particle motion?

In the molecular kinetic theory, it is believed that particles in liquids are not equally densely located. The gaps between them can be of various sizes, some such that another particle can fit there. This allows them to jump from denser places to freer ones. These jumps of particles from one stable position to another explain the fluidity property of liquids.
