Sound generally refers to a disturbance that is audible to the human air. In air, like in any gas, such disturbances propagate as a compression and rarefaction 'pulse'.
Watch a traffic jam from a distance - you see the 'bunching' of cars propagate away from the head of the traffic. Then, when the initial blockage is removed (light goes green) the bunched cars separate out again (the rarefaction).
In solid media you can have both compression/rarefaction waves and also transverse waves. These can be visualized by (mentally) taking a long and rather slack spring, stretching it out, and shaking one end from side to side.

Which can sound NOT travel through?
Vacuum as sound needs badly a material medium to get it propagated.
How do sound waves spread or propagate from the source toward the space around it?
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.
How do particles in a sound wave move?
The move by expansion and Contraction of the medium by which they are propagated. It is transmitted in air as a longitudinal wave- which means its direction is in line with the movement of the medium.
Is sound a gas?
Sound is a kind of energy. It is the vibrational energy being propagated in the form of longitudinal waves. So sound is not a gas but it needs a gas or other medium to propagate in.
Water waves are longitudial waves?
Waves formed on the surface of water are transverse in nature. But sound waves when propagated through water medium then that will be in longitudinal nature. Cannot be seen on the surface.
Can sound be propagated in vacuum give reason?
No. Sound requires a medium to propagate through
Which can sound NOT travel through?

Can sound be propogated in vacuum give reasons?
Sound cannot be propagated in a vacuum because it needs a medium to be propagated from one end to another which lacks in a vacuum.
How do sound waves spread or propagate from the source toward the space around it?
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.
Is a mechanical wave a sound wave?
Yes, a sound wave is a mechanical wave. Sound waves need a medium (like air) to travel through. The energy of the wave, the mechanical energy, is transferred into the medium through which it is propagated.
How do particles in a sound wave move?
The move by expansion and Contraction of the medium by which they are propagated. It is transmitted in air as a longitudinal wave- which means its direction is in line with the movement of the medium.
Is sound a gas?
Sound is a kind of energy. It is the vibrational energy being propagated in the form of longitudinal waves. So sound is not a gas but it needs a gas or other medium to propagate in.
What is light transmission?
Light is also a kind of energy. It is transformed not as mechanical wave. Because mechanical wave definitely needs a material medium to get propagated. Sound energy is transmitted only as a mechanical wave. Without air medium sound cannot be propagated. But light does not need such material medium. It can pass even through free space in the form of electromagnetic wave. The general concept is: When any disturbance is made any where at any time in the space that would be propagated to other places. This is what we call transmission of light disturbance.
What is the importance of trigonometry in the field of sound?
The compression and rarefaction of the medium in which the sound is propagated can be modelled by a sine curve. You can see a half-wave in the vibration of a string on musical instruments or even a stretched elastic band.
What is a disturbance or vibration propagated from point to point in a medium or in space?
A wave
Why does sound travel qiuckest through a solid?
Sound is a mechanical wave. It requires a medium for propagation. Since the particles in a solid are close together, the sound energy is propagated way faster in solids rather than liquids and gases whose particles are not as close.
What if the molecules from a sound wave are compressed?
Nothing. That IS how a sound wave is propagated.
