Study Notes

Particle Model of Matter

Solids consist of closely packed particles, resulting in a definite size and shape.
Liquids have particles that are slightly apart, allowing them to take the shape of their containers.
Gases are composed of particles separated by greater distances, which means they have no definite size or shape and are highly compressible.

Sound Transmission

Sound is generated by the vibration of particles and can travel through solids, liquids, and gases.
Sound cannot propagate in a vacuum or empty space, as there are no particles to vibrate.
In outer space, where particle density is extremely low, sound cannot be heard.

Evidence of Sound Travel

Ancient tribes placed ears on the ground to detect sounds of intruders, demonstrating sound travel through solids.
Children use makeshift telephones made from cans and string, showing sound can travel through string (a solid).
Dolphins are known to respond to sounds traveling through water, indicating effective sound transmission in liquids.
Sounds made in a swimming pool, such as tapping at the bottom, can be heard, illustrating sound travel underwater.
Communication in air relies on the movement of sound waves through gases.

Delay of Sound

The delay in sound heard during fireworks is attributed to the distance sound waves must travel before reaching the observer.

Description
