Explanation:

According to the kinetic - theory of matter, particles in a solid are closely packed and have strong intermolecular forces. They vibrate in place about their fixed positions due to thermal energy. They do not move around at high speeds like gas particles, are not completely motionless, and do not slide around and tumble over each other like liquid particles.

Vibrate in place.
