Question

in which state of matter do the particles take on a random arrangement?
solid
liquid
gas
both solid and liquid
both liquid and gas

Explanation:

To determine the state of matter with randomly arranged particles, we analyze each state:

• Solid: Particles are closely packed in a regular, ordered arrangement (e.g., crystalline structure).
• Liquid: Particles are close together but can move past each other, with a random (non - ordered) arrangement.
• Gas: Particles are far apart and move freely, also having a random arrangement.
• For the "both" options: Solids have ordered arrangements, so "both solid and liquid" is incorrect. Liquids and gases both have random particle arrangements.

Answer:

E. both liquid and gas
