Which one of the following statements best explains why convection does not occur in solids? A. The molecules in a solid are not free to move throughout the volume of the solid. B. Molecules in a solid vibrate at a lower frequency than those in a liquid. ...

The solubility of a given solute in a given solvent typically dependson temperature. For many solids dissolved in liquid water, solubility tends to correspond with increasing temperature. As water molecules heat up, they vibrate more quickly and are better able to interact with and break apart the...
Groups of flux tubes can even have solid and liquid phases, in analogy to regular (actual) matter. One of the more commonly seen quasi-particles is the “electron hole”, which is just a notably absent electron. The tiles are real things, but the vacant square is just...
Sound is technically just a vibration of particles. Most people generally think of vibrations in the air when they think of sound, but sound can also travel through solids and liquids. Therefore, flesh and bone can function as a speaker, because particles in a solid can vibrate too. In fact...
Tie knots in the ends of the string so the string doesn't pop out. Why doesn't your telephone work when you let the string hang loosely? When you use the string phone, your voice makes the air particles in the cup start to vibrate. These vibrations then make the bottom of the cup ...
A mechanical wave is transverse when all the particles of the medium, which are solid or liquid (and never gas), vibrate perpendicularly at right angles, up and down, and continue to move in the direction of the wave. For example, the ripples on the surface of a lake are transverse wave...
