Which statement best describes the motion of the molecules in a solid object?
A
The molecules are completely stationary and do not move at all.
B
The molecules move rapidly and independently throughout the entire volume.

Guida verificata passo dopo passo1
Understand the nature of molecular motion in different states of matter: solids, liquids, and gases.
Recall that in solids, molecules are tightly packed in a fixed, orderly arrangement, which restricts their movement.
Recognize that molecules in solids do not move freely or slide past each other, unlike in liquids or gases.
Identify that the primary motion of molecules in a solid is vibration around fixed positions within the lattice structure.
Conclude that the best description of molecular motion in a solid is that molecules vibrate in fixed positions but do not move freely.
