Question

which of the following correctly pairs a phase of matter with its description? a solid. particles have no motion. b gas. particles have higher amount when in the liquid phase. c liquid. particles expand to fill any container in which they are placed d liquid. particles are more strongly at another than when in the solid phase.

Explanation:

In a solid, particles vibrate in place, not having no motion (so A is incorrect). In a gas, particles have more kinetic - energy and are more spread out compared to liquids, so they have a higher amount of motion when in the gas phase relative to the liquid phase (B is correct). Liquids take the shape of the container they are in but do not expand to fill it completely like gases do (C is incorrect). Particles in a solid are more strongly attracted to one another than in a liquid (D is incorrect).

Answer:

B. Gas: Particles have higher amount of motion when in the gas phase compared to the liquid phase.
