## How fast does a solids molecules move?

Solids – vibrational (and rotational); moving very slowly. Liquids – vibrational, rotational, and translational; moving quickly. Gases – vibrational, rotational, and translational; moving very quickly.

Do solids particles move fast?

Students should realize that if you heat a solid, the atoms or molecules move faster and move further apart. If you cool a solid, the molecules move more slowly and move a little closer together.

Are solids fast?

Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids.

### Does sound travel faster through solids?

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

### Why do solids have definite volume 12?

(a) Solids have definite shape and definite volume because the molecules in solid are closely packed and in fixed positions. The molecules can vibrate but do not move around which keeps the shape and volume definite.

When do particles move slowly in a solid?

When you have little to no heat, the particles are moving very slowly, so slowly that they atomic attractions result in bonds that are difficult to break without adding energy. At this stage, this is known as a solid. In a solid, the particles are vibrating.

How is a liquid different from a solid?

liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern. Particles in a: gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.

#### What happens to molecules when you cool a solid?

If you cool a solid, the molecules move more slowly and move a little closer together. Show an animation to help students compare atoms and molecules in solids and liquids.

#### How are liquid particles packed in a solid?
