Question

what is the difference between an amorphous solid and a crystalline solid?
○ amorphous solids have both liquid and solid particles while crystalline solids have only solid particles
○ crystalline solids have both liquid and solid particles while amorphous solids have only solid particles
○ amorphous solids have particles that are randomly arranged while crystalline solids have particles in
○ crystalline solids have particles that are randomly arranged while amorphous solids have particles in

Explanation:

To determine the correct option, we recall the definitions of amorphous and crystalline solids. Amorphous solids (like glass) have particles in a random, non - repeating arrangement. Crystalline solids (like salt, diamond) have particles arranged in a highly ordered, repeating 3 - D pattern (a crystal lattice).

• The first two options are incorrect because neither amorphous nor crystalline solids contain liquid particles. Solids, by definition, have particles in a relatively fixed position (compared to liquids or gases).
• The fourth option is incorrect as it reverses the particle arrangement characteristics of the two types of solids.
• The third option (even though the sentence seems cut off, from the visible part) correctly states that amorphous solids have randomly arranged particles while crystalline solids have an ordered (implied by the context of the option, as crystalline solids have particles in a regular pattern) arrangement.

Answer:

The correct option is the third one: "Amorphous solids have particles that are randomly arranged while crystalline solids have particles in" (assuming the full option would state the ordered arrangement of crystalline solid particles, and this is the only option that correctly reflects the particle arrangement difference between the two types of solids).
