The physical process by which sound moves through a medium such as air molecules for example, involves vibrations wherein compressions and de-compressions (rarefactions) are manifest and transport the wave energy through the medium while leaving the air molecules more or less in the same place afterwards. The concept should generally be understood to be not so much the gross motion of particles from source to destination, as rather the motion of the wave energy itself from the source. As such it would be better to say that air particles vibrating quickly or with a higher frequency are perceived as a higher note or pitch, and more slow vibrations indicative of a lower tone or pitch.
A slow mass movement of individual sediments is a creep. It happens so slowly that you cannot see it happening and it can go on for years.
When the temperature falls, the particles in a substance slow down and lose energy. This can cause the substance to contract or solidify, depending on the type of material and how much the temperature decreases.
When matter loses energy, its particles slow down. This decrease in kinetic energy leads to a decrease in particle movement and ultimately a decrease in temperature.
The sound wave will travel faster in the medium where particles of matter are further apart because there will be less resistance and the particles are more spread out, allowing the wave to propagate more easily.
When a substance freezes, its particles slow down and come closer together, forming a more structured and rigid arrangement. This results in the substance transitioning from a liquid state to a solid state.
they slow down.
it becomes a solid.
As a medium cools down, the speed of sound generally decreases. This is because the particles in the medium slow down and have less energy to transmit waves. The relationship between temperature and the speed of sound varies depending on the medium.
When liquids cool, the particles tend to tighten up, or get really close together, and slow down.
When molecules freeze the rate of speed they go at tends to slow down
When a gas turns into a liquid, its called condensation. The particles slow down and move closer together.
As the liquid in the can cools down after being heated, the particles within the liquid lose energy and slow down, resulting in their closer proximity to each other. This causes the liquid to contract and become denser.
particles in the air slow it down and cause it to stop eventually
The molecules of water slow down and eventually stop when you hit absolute zero.
They slow down and come closer together forming a liquid. Then further cooling will produce a solid.
When thermal energy is taken away from matter, the particles will lose energy and slow down, leading to a decrease in temperature. As the particles slow down, they may eventually come together and form a solid if enough energy is removed. This process is known as cooling or condensation.
