Vibrational Motion | MCQs

Explanation

In a solid, the particles (atoms, molecules, or ions) are closely packed and vibrate in place, holding their position in the crystal lattice.

This vibration is due to thermal energy, and the particles oscillate around their fixed positions.

Key Points:

• In a gas, particles are widely spaced and move freely.
• In a liquid, particles are close together but move past each other.
