Which statement best describes the movement of molecules in liquids compared to solids and gases?

• A. Molecules in liquids do not move at all.
• B. Molecules in liquids move freely past one another but remain close together.
• C. Molecules in liquids are fixed in place and only vibrate.
• D. Molecules in liquids are far apart and move independently at high speeds.

Answer: (B)

Verified step by step guidance

1. Understand the states of matter and how molecular motion differs in solids, liquids, and gases.
2. Recall that in solids, molecules are tightly packed and primarily vibrate in fixed positions.
3. Recognize that in gases, molecules are far apart and move independently at high speeds.
4. Focus on liquids: molecules are close together but not fixed, allowing them to move past one another freely.
5. Conclude that the best description for molecular movement in liquids is that molecules move freely past one another but remain close together.
