Sound is only produced through vibrations. So if there was no air, there would be no sound. In other words, sound needs a medium to travel through, because it needs something to vibrate. The denser the medium, the faster and farther it travels.
Sound Waves
Sound Waves
Compressional waves caused by colliding air molecules are known as sound waves. These waves travel through the air by creating areas of high pressure (compression) and low pressure (rarefaction), which result in the perception of sound. The frequency of these compressional waves determines the pitch of the sound, while the amplitude determines the volume.
You are wrong. Thunder is the noise made when the lightning causes the air to heat up and expand suddenly. When this explodes we hear the sound we call thunder.
Sound propagate in the form of waves. Waves have energy so they propagate through the medium. Unless you can reflect it back , or damp the sound wave using some or the other way, it is virtually impossible to "stop" a sound in mid air
Yes, as air temperature increase so does the speed of sound. This is due to the individual air particles having extra kinetic energy at higher temperatures, allowing vibrations of sound waves to pass easily.
Sound travels by molecules colliding with each other to pass on the wave. Therefore sound travels better through solids than air because solid are denser, meaning the molecules are closer together. This helps them collide more readily.
When you clap your hands together, you create a compression wave, also known as a sound wave. This wave is produced by the vibrations of your hands colliding and propagates through the air as a pressure disturbance that we perceive as sound.
The colliding air masses in Tornado Alley are warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. This collision is just part of the recipe for tornadoes.

No, a crunch sound is not a small sonic boom. A crunch sound is typically caused by objects breaking or colliding, creating a sharp, loud noise. A sonic boom, on the other hand, is a loud noise generated by an object as it travels faster than the speed of sound through the air.
particles in the air slow it down and cause it to stop eventually
