Question

particle models
below are three particle models illustrating different states of matter
choose the correct answer.
which of these models represents an object in which the particles move very little and only vibrate in place?
model a (a solid)
model c (a gas)
model b (a liquid)

Explanation:

In solids, particles are closely packed and have strong intermolecular forces. This restricts their movement to only vibrating in place. Model A shows closely - packed particles, characteristic of a solid. Model B represents a liquid where particles can move past each other more freely, and Model C represents a gas where particles are widely spaced and move freely.

Answer:

Model A (a solid)
