What is the area of a sound wave where particles are less dense?
Rarefaction
The less dense region of a compression wave is called?
The less dense areas created as a sound wave propagates are called rarefactions.
Do heated air particles become more or less dense?
Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
Does sound increase or decrease with altitude?
With no air, you get no sound, so guessing it decreases, also sound travels slower in a less dense medium.
Why does sound travel faster in warm?
Because the molecules are less dense and they vibrate faster letting sound travel faster
What is the area of a sound wave where particles are less dense?
Rarefaction
Diffusion is the spreading of a?
...more dense particles to an area of less dense particles
Why does sound go faster through air than water?
Air particles are much less dense than water particles, so the vibrations of sound can travel through air more quickly.
What happens to particles in a medium when sound energy travels through it?
slows down in denser mediums & speeds up in less dense ones this explains why ur voice is so high pitched when u inhale a less dense gas like helium & why sound is deep & distorted underwater.
When a gas expands whether its density increases or decreases?
the density decreases because the particles spread out and so less particles occupy the same amount of area meaning the substance is less dense.
Why does sound travel faster through hot air than cold air?
Hot air is less dense so there are less interactions to slow the transmission, and less 'inertia' of particles.
When sound travels in gas is it more dense or less dense?
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
Why is sound faster in steel than gold?
because gold is made up of dense particles, and the denser the particles are, the more they resist in movement so it take more energy to move them which result in a slower transfer of sound energy. In comparison, steel is less dense than gold which makes sound transfer faster in steel than in gold
Diffusion occur because what?
Particles have to move from a more dense area to a less dense are.
What is an area of crowded particles followed by widely spaced particles?
An area of crowded particles followed by widely spaced particles is known as a density wave. In a density wave, particles are closely packed together in one region, creating a dense area, and then spread out and become less concentrated in another region, resulting in a sparse area. This pattern repeats periodically, forming a wave-like structure.
Do diamonds become less dense when heat is added?
Yes. They do become less dense provided that the diamond melts. The particles in liquid are less close to each other as compared to in a solid.
What Heated water becomes less blank as it and temperature rises and it and particles spread apart?
It becomes less dense.
