Atoms and molecules vibrate at fixed positions, but the direction and amplitude of the vibration of each atom and molecule is random, so there is no net vibration of the solid object. Upvote • 1 Downvote Comments • 3 Hailey P. So, you’re saying the movement of atoms and molecul...
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 solids, the intermolecular forces are strong, which means that the molecules are closely packed together. They can only vibrate in their fixed positions, which contributes to the solid's definite shape. 3. Understanding Gases: - In contrast, gases do not have a definite shape or volume...

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...
On Venus, the pitch of your voice would become deeper, because vocal cords would vibrate much more slowly in the thicker Venusian atmosphere. But sounds would travel more quickly through the soupy atmosphere. According to Dr. Leighton, humans would sound like bass Smurfs. Mars would sound a li...
