What is the Speed Of Sound & How does it work?

The speed of sound in air is influenced by both temperature and humidity. At standard atmospheric pressure, the speed of sound increases with temperature due to increased molecular motion.

c = sqrt{gamma R T}
c = speed of sound, Ξ³ = specific heat ratio, R = gas constant, T = temperature in Kelvin

Humidity affects the speed of sound because water vapor has a lower molecular weight than dry air. This results in a slightly higher speed of sound in humid air compared to dry air at the same temperature.

Frequently Asked Questions
How does temperature affect the speed of sound?
The speed of sound increases with temperature due to increased molecular motion.
What is the formula for calculating the speed of sound?
c = √(γRT), where c is the speed of sound, γ is the specific heat ratio, R is the gas constant, and T is the temperature in Kelvin.
How does humidity affect the speed of sound?
Humidity increases the speed of sound because water vapor has a lower molecular weight than dry air.
What is the standard atmospheric pressure for this calculation?
The calculation assumes standard atmospheric pressure, which is typically 101.325 kPa.
Can I use Celsius instead of Kelvin for temperature?
No, you must use Kelvin for the temperature in the formula c = √(γRT).
How does altitude affect the speed of sound?
Altitude affects the speed of sound because it influences air pressure and density. Generally, the speed of sound decreases with increasing altitude.
What is the specific heat ratio (Ξ³) for dry air?
The specific heat ratio (Ξ³) for dry air is approximately 1.4.
