Question

which statement best describes the arrangement of particles in a solid? * 1 point
o particles move freely with no fixed pattern.
o particles are loosely connected and flow easily.
o particles are tightly packed in a regular pattern.
o particles float independently of each other.

Explanation:

To determine the correct statement about particle arrangement in a solid, we recall the properties of solids. In a solid, particles are closely packed in a regular (crystalline) or sometimes amorphous (less regular but still tightly packed) pattern. They vibrate in fixed positions, not moving freely (which is for gases/liquids) or floating independently (gases) or being loosely connected (liquids). So the option "Particles are tightly packed in a regular pattern" matches the solid's particle arrangement.

Answer:

B. Particles are tightly packed in a regular pattern (assuming the second option is labeled B; if the original labels were different, adjust the identifier, but based on the order, the second option is the correct one describing solids' particle arrangement).
