Notice: The speed of sound changes with temperature and
a little bit with humidity − but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading.
The temperature indication, however, is absolutely necessary. The speed of sound at 25 degrees Celsius (77 degrees Fahrenheit) is 346 meters per second. That is 1136.113 feet per second.

T = Temperature.
Speed of sound in air at 20 °C is c ≈ 331 + 0.6 × 20 = 343 m/s.

What is the speed of sound at 30 degrees celsius?
The speed of sound at 30 degrees Celsius is approximately 343 meters per second in dry air. However, the speed of sound can vary depending on factors such as humidity and air pressure.
What is the speed of sound in air at 0 degrees Celsius and absolute pressure of Bar?
The speed of sound in air at 0 degrees Celsius is approximately 331.5 meters per second. The speed of sound in air is also influenced by factors such as humidity and pressure. At standard atmospheric pressure (1 bar), the speed of sound is around 331 m/s.
Which travels faster sound at 15 degrees Celsius or 30 dgrees Celsius?
Sound travels faster in warmer temperatures. At 30 degrees Celsius, sound will travel faster than at 15 degrees Celsius. This is because sound travels faster in warmer air due to the higher average speed of air molecules.
Does sound travel faster in air at 20 Celsius or at 0 Celsius?
Sound travels faster in air at 20 degrees Celsius compared to 0 degrees Celsius. This is because the speed of sound increases with temperature, as the molecules move quicker and can transmit sound waves more efficiently.
What would happen to the speed of sound if the air temperature dropped below 0 degrees celsius?
If the air temperature dropped below 0 degrees Celsius, the speed of sound would decrease. This is because sound travels faster in warmer air due to the increased kinetic energy of the air molecules. As temperature decreases, the speed of sound decreases as well.
What is the speed of sound in air at 0 degrees Celsius?
The speed of sound in air at 0 degrees Celsius is approximately 331 meters per second.
Compare the speed of light with the speed of sound at 0 degrees celsius?
The speed of light has nothing to do with the temperature of the vacuum. It is c = 299 792 458 meters per second. The speed of sound has much to do with the temperature of the air. At 0 degrees Celsius the speed of sound in dry air is c = 331.29 meters per second.
What would happen to the speed of sound if the air temperature dropped below 0 degrees celsius?
If the air temperature dropped below 0 degrees Celsius, the speed of sound would decrease. This is because sound travels faster in warmer air due to the increased kinetic energy of the air molecules. As temperature decreases, the speed of sound decreases as well.
What is the speed of sound in dry air at 7 degrees celsius?
The speed of sound in dry air at 7 degrees Celsius is approximately 331 meters per second. This value can vary slightly depending on factors like humidity and air pressure.
What is the speed of sound at zero degrees Celsius?
The speed of sound at zero degrees Celsius is approximately 331.5 meters per second (m/s) in air. This speed can vary depending on factors such as humidity, pressure, and the composition of the medium through which the sound is traveling.
What is the speed of sound in air when the air has a temperature of 20 degrees Celsius?
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.
What is the speed of sound in glass at 29 degree Celsius?
The speed of sound in glass at 29 degrees Celsius is approximately 4,850 meters per second.
How many miles per hour does a super sonic engine go?
Depends on the temperature of the surrounding air through which the vehicle is moving. At 21 degrees Celsius the speed of sound is 770mph. Between 11,000m and 20,000m, the air temperature is about -60 degrees Celsius which equates to the speed of sound being 660mph.
What is speed of sound in meter per second?
The speed of sound is dependent on the temperature and not on the air pressure. At 20 degrees celsius the speed of sound is 343 m/s.
What is the speed of sound in medium air?
The speed of sound in medium air at room temperature is approximately 343 meters per second, or about 767 miles per hour.
When the temperature is 25 degrees Celsius what is the approximate velocity of a sound wave traveling through the air?
The approximate speed of sound in air at 25°C is 346.45 m/s².
The speed of light and the speed of sound?
The speed of air at 20 degrees Celsius is 343 meters per second. The speed of light is 299 792 458 meters per second.
