Will cold air particles transmit sound at a higher speed than hot air particles?

colder air is more dense than warmer air. As a result it is harder for the sound to travel through the cold air and the speed of sound is slower in cold air compared to warm air.

When is speed of sound the greatest?
The speed of sound is greatest in solids, as the particles are closer together and can transmit vibrations faster. In general, the speed of sound increases with an increase in density and elasticity of the medium.
Does the speed of sound increase when temperature increases?
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.
Summarize the physical reasons that sound waves travel at different speeds through liquids and gases?
Sound waves travel fastest through solids, then liquids and gases. This is because sound waves requires medium in order to travel. Solid's particles are very tightly packed with each other thus sound gets more medium to travel faster. Liquid particles are less close to each other and gas is the least. Temperature also increases the speed of sound. higher the temperature, higher the speed of sound.
A sound wave moves from a medium where particles of matter are closely packed to a medium where particles of matter are further apart How do you expect the sound wave to travel differently?
The wave will move faster, increasing its speed.
Why does sound move faster through stone than water?
sound moves faster though stone than water because stones particles are closer together and vibrate faster. +++ We can add that in general, the denser the material the higher the speed of sound through it.

What transmit sound the fastest?
The speed of sound depends only on the material it's traveling through, not on the source of the sound. In general, the speed is higher in more-dense media, like steel, water, and rock, then it is in less-dense media, like air.
How the normal shock is obtained?
An intuitive approach: As a moving object travels through a fluid, the fluid particles hitting the object transmit information with the speed of sound to the surrounding fluid particles about their encounter with the body. If the speed of the moving object is smaller than the speed of sound the surrounding particles have time to react and "get out of the way"(i.e. the streamlines begin to curve to compensate for the presence of the body) since the perturbation caused by impact propagates with speed of sound. But if the moving object travels with a speed higher than the speed of sound then the surrounding particles can't react(information about the collision hasn't arrive to them prior to the object reaching them). That's how the shock wave is formed. Now, the normal shock is a special case when the speed of the moving object is exactly the speed of sound (or Mach number equals one). In this case you can imagine that the molecules in front of the object form a "wall" perpendicular to the moving direction of the object.
What is the speed of sound in concrete?
Between 3200 and 3600 m/s, the closer together the particles are in a substance are, the faster sound can travel through it. This is why these values are much higher than the 343 m/s, the speed of sound in air.
Does the speed of sound increase when temperature increases?
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.

What has the higher speed of sound?
It Is solids like metals. Sound has a high speed n metals.
When is the speed of sound near the ground less than the speed of sound higher up?
If the speed of sound near the ground is less than the speed of sound higher then in this special case the temperature at the ground must be less than the temperature higher up. Usually the temperature at the ground is warmer than the temperature high up in the sky. The speed of sound changes mainly with the temperature.
What tree properties of a medium affect the speed of sound?
The speed of sound is affected by 3 properties: Elasticity and Density of the medium through which the sound waves travel, and the temperature of the medium. Media with higher elasticity, like iron, for instance, transmit sound faster. (Elasticity is the ability of a substance to return to its original shape after being deformed by a force applied to it. Rubber has high elasticity, too.)
A sound wave moves from a medium where particles of matter are closely packed to a medium where particles of matter are further apart How do you expect the sound wave to travel differently?
The wave will move faster, increasing its speed.
The greater the speed gas particles in a container the?
The greater the speed of gas particles in a container, the higher the overall average temperature and kinetic energy of the gas particles. And if volume was held constant, higher the pressure.
How does air tempurature affect the speed of sound?
Sound waves travel through particle vibration, and when the temperature is high, the particles vibrate faster, thus the sound must travel faster with particles.
