The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
Statement: The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature, because the ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude.
Notice: The ratio p_ / ρ (static air pressure to air density) is really always constant.
Speed of sound(V) in air is proportional to square root of absolute temperature. If temperature increases speed of sound in air increases and vice versa.
V = sqrt(γRT/M)
where γ = Cp/Cv
R - gas constant
M - average molar mass of air.
All should be taken in same system of units.
The way in which the speed of sound through air is affected by temperature is demonstrated by the formula: v= (331.5 + 0.606 x T) m/sec, where T = temperature.
In general sound travels faster through warm air than through cold.

Temperature has not affect on the speed of sound.
When the temperature of the air is increased by 4 times then speed of sound will be increased by 2 times. Same way if it is decreased by 9 times then speed will be decreased by 3 times.
It increases the speed of sound.
It is the speed of sound in a fluid at stagnation conditions. For example, if you have air flowing at some speed V with a temperature T and pressure P, the speed of sound in the air at those conditions will be = sqrt(kRT). k is the ratio of specific heats (approx. 1.4), R is the ideal gas constant for air (approx. 0.2870 kJ/kg/K). If that moving air hits an object and stagnates, the pressure, temperature, and density of the will increase to the stagnation conditions by an amount proportional to the air's initial velocity. The stagnation speed of sound will be the speed of the sound at those stagnation conditions (most importantly the speed of sound at the stagnation temperature).
Of course it does. One thing can be said about air entrainment everything affects it in concrete. High temperature can lower the effectiveness of air entrainment products. Typically requiring a higher dosage of air entrainment to get the desired air content.
No. The temperature of the unit would be at the ambient temperature of the room.
The theoretical max speed of a helicopter is based on the speed of the main rotor through the air, since conventional airfoils essentially quit lifting at close to the speed of sound. Knowing that, let's assume the main rotor's tip speed moves through the air at 400 mph while in a hover. Now, as the vehicle begins to move forward, that forward motion is added to the existing tip speed. Since the speed of sound at sea level is around 750 mph, our example bird shouldn't be able to go any faster than 350 mph. Realistically, our example wouldn't be able to travel even that fast, since air traveling across an airfoil (the main rotor) accelerates across the top surface, thus cutting into our theoretical top speed. That being said, airfoil design is constantly evolving, allowing incremental improvements in efficiency, speed, and noise reduction.
Air will flow out of a building when the outside temperature is warmer.
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
The speed of sound is dependent on the temperature. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Speed of sound increases, when temperature increases. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
The speed of sound is 331 metres per second at zero degree centigrade and at sea level (air pressure and temperature affect the speed of sound).
Pitch of sound in air does not affect the speed of sound.The speed of sound in air is also not affected by atmospheric pressure.Temperature does affect the speed of sound in air.Similar statements are not true for liquids or solids. It stops being true for gasses when pressure and temperature are near the point that the gas will liquify.
Think mainly of the temperature and a little bit of the humidity. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
It is the medium, which is usually air and it is the temperature. Look at the Link: "Speed of Sound in Air and the effective Temperature".
The speed of sound has neither to do with the sea level nor with Tucson. Speed of sound has mainly to do with the temperature of the air. Look at the link: "Speed of Sound in Air and the effective Temperature".
I guess you refer to the speed of sound. The speed of sound depends on the material sounds goes through, as well as temperature, pressure, humidity, among others. For example, the speed of sound in air is around 350 meters/second; in some other materials it can be several times as fast.
Pressure doesn't affect the speed of sound because the static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature and because the ratio p_ / ρ is always constant whether on a high mountain or even on sea level altitude. Therefore, the speed of sound stays constant and is only dependent on the changing temperature.
The speed of sound in air has really nothing to do with the sea level and its atmospheric pressure. Speed of sound is dependent on the temperature. Look at the link: "Speed of Sound in Air and the effective Temperature".
Some factors that affect the speed of sound waves are density of medium, temperature, direction of wind, and humidity. Remember that a sound wave is just a pressure disturbance that travels through a medium by particle interactions. The nature of the medium will affect the sound waves velocity.
