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. ...
"In a solid, the particles can only vibrate about a fixed position." True or False. The magnet is not touching the electrons, yet something is causing them to move. Explain what you think is happening. Do we see the wave properties of matter in our macroscopic world? If so, why? If...
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 solute.
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 vibrate, and make the string move in the same way. ... When the string is loose,it can't vibrate nearlyas well, which means sound can't...

(compressional wave). Making Sound Waves • When an object vibrates, it exerts a force on the surrounding air. • The air where the molecules that are more dense is called a compression. • The region of lower density is called a rarefraction. • A sound wave is described by its...
Ever wondered what homeopathy truly is? Who better to ask than Boiron? On their website, Boiron (the largest manufacturer of homeopthics) explains: Homeopathy is a therapeutic method that uses natural substances to relieve symptoms. It derives from the Greek wordshomeo, meaning “similar,” and...
Sounds travel through solids "best" in that the sound wave moves very quickly. However, it also takes more energy to vibrate a solid object,... Learn more about this topic: Sound Energy: Lesson for Kids from Chapter 6/ Lesson 42
