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. ...

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...
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, solids transmit sound faster than air and water, because the particles in a solid ...
The atom can’t give away part of the energy and just vibrate a little less. When the atom does give up its kinetic energy it stops vibrating and an atom next-door picks up that energy (all of that energy) and starts oscillating in turn. This one-step-up-from-the...
found that the 'plink, plink'soundproduced by a water droplet hitting a liquid surface is caused not by the droplet itself, but by the oscillation of a small bubble of air trapped beneath the water's surface. The bubble forces thewater surfaceitself to vibrate, acting like a piston to dri...
Laser thermometers are actually infrared thermometers. The laser simply provides a means to aim the thermometer. The molecules that make up objects are vibrating constantly; the hotter the molecule is, the faster it vibrates, producing invisible light in the form of infrared energy. Infrared (IR)...
As they travel through it, they make the molecules inside it vibrate more quickly. Vibrating molecules have heat so, the faster the molecules vibrate, the hotter the food becomes. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up. Do microwaves cook ...
