Question

question 3 which particles are not in fixed positions, so they are free to move past each other but are still bound to each other? solids liquids c gases ice

Explanation:

To solve this, we analyze the particle arrangements:

• Solids: Particles are in fixed, ordered positions (vibrate in place), so not free to move past each other.
• Liquids: Particles are close but not in fixed positions, can slide past each other while still being bound (due to intermolecular forces).
• Gases: Particles are far apart, move freely and are not strongly bound.
• Ice: Is a solid (frozen water), so particles are in fixed positions.

So the particles described match liquids.

Answer:

B. Liquids
