Question

the models below represent atoms in different phases. what type of model are these images? three boxes with different arrangements of circles particle models computer simulation models mathematical models analogy models

Explanation:

Particle models represent atoms or molecules in different phases (solid, liquid, gas) by showing the arrangement and spacing of particles. The images here show atoms in different arrangements (close - packed for solid - like, more spread for liquid/gas - like), which matches particle models. Computer simulation models would be digital simulations, mathematical models use equations, and analogy models use comparisons to unrelated things, so these are particle models.

Answer:

A. Particle Models
