longitudinal waves spread apart as they go
Longitudinal waves push particles together by compressing them and spread them apart by rarefying. Sound waves are an example of longitudinal waves.
Two forces that act on particles inside a nebula are gravity, which pulls particles together to form new stars and solar systems, and radiation pressure, which pushes particles apart due to the energy emitted by hot stars within the nebula. These forces must be balanced for a nebula to maintain its structure and not collapse or dissipate.
In hot air, the particles have higher kinetic energy, causing them to move faster and spread out more, resulting in a decrease in density and the particles being farther apart.
Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
The particle theory suggests that when solids, liquids, and gases are heated, the particles within them gain kinetic energy and move faster. In solids, the particles vibrate more vigorously but remain in fixed positions. In liquids, the particles move more freely but are still close together. In gases, the particles move rapidly and are spaced far apart.

high sound particles are near, and low sound as far apart particles.
steam is a gas so the particles are far apart
The particles of a solid are close together and the particles of a liquid are slightly farther apart.
There's no force that pushes electrically neutral objects apart, but if the objects in question have a net charge, then the force known as electromagnetism will either push similarly charged objects apart, or pull oppositely charged objects together.

Regions in a sound wave where particles are farthest apart are called rarefactions. In a sound wave, these rarefactions alternate with compressions, where particles are closest together. Together, these alternating regions create the wave’s propagation through a medium.
far apart because heat always has more kinetic energy
No, they are not packed tightly together. The particles in solids are. In gas, they move in random motion and are the furthest apart, compared to solids and liquids. Hope this helps :)
Particles in a gas are not closely packed together; they are much farther apart compared to particles in liquids or solids. Gas particles move freely and rapidly, filling the entire volume of their container.

the particles get closer together because my class just talked about that stuff!!
