In the gas phase, the particles spread out to completely fill their container.
In a homogeneous mixture particles are spread evenly.
The region of spread out particles in a wave is called the trough. This is where the particles are at their lowest point of displacement from their equilibrium position.
Rarefaction is the part of a longitudinal wave where the particles are spread apart.
Particles are spread out to the maximum of the space available.
particles of the medium
A longitudinal wave has areas where particles are spread out. In this type of wave, particles move parallel to the direction of the wave propagation, causing areas of compression (particles close together) and rarefaction (particles spread out). Sound waves are an example of longitudinal waves.
Body spray particles will spread quicker than sugar particles because body spray particles are lighter and smaller, allowing them to disperse more easily through the air. Sugar particles are larger and heavier, making them less likely to spread quickly and over a larger area compared to body spray particles.
The rarefaction is the area of a longitudinal wave where the particles of the medium are spread out. This region is where the particles are farther apart compared to the rest of the wave.
When particles separate and spread evenly throughout a mixture, it is called diffusion.
Heat makes particles spread out and the particles spread out in the ballon therfore making the ballon burst.
compressional waves
Sound does not spread out in particles but in waves. Imagine dropping a pebble in a still lake...and that is how sound waves spread out. Sound waves can also reverberate through harder materials; however, soft materials absorb the vibrations.
