Question

Specific term required. Fundamental measure theory is a form of DFT applied to mixtures of these objects. A system of these objects simulated by the Lubachevsky-Stillinger algorithm undergoes jamming as these objects are compacted. In the first usage of molecular dynamics, Alder and Wainwright simulated these objects in a box. The excluded volume of these objects (-5[1])is eight times their volume, and their second (-5[1])virial coefficient is equal to four. (-5[1])Formally, these objects are defined as having a pairwise interaction potential of (*) infinity when distance is less than some sigma, and zero potential when distance is at least sigma. (-5[1])In kinetic molecular theory, particles have no volume and are assumed to be these objects with a two-word name. A common approximation in statistical mechanics is to (-5[1])model particles as, for 10 points, what idealized particles that cannot overlap in space? (0[1])■END■ (10[1]0[4])

ANSWER: hard spheres [or hard disks; accept hard core model; accept rigid spheres; prompt on particles; prompt on spheres or balls; prompt on disks]
