The speed of sound in air changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary.
At the temperature ϑ = 20°C the speed of sound is c = 331.3 + 0.606 × 20 = 343.42 m/s.Often the easy calculation will do: c ≈ 331 + (0.6 × ϑ) = 343 m/s.

What is the approximate velocity of sound in the air?
The approximate velocity of sound in air at room temperature is about 343 meters per second (1235 kilometers per hour). The actual velocity may vary based on factors like temperature, humidity, and air pressure.
When the temperature of the air is 25 degrees the velocity of a sound wave traveling through the air is?
At 25 degrees Celsius, the velocity of sound in air is approximately 346 meters per second. This value is calculated using the formula: velocity = 331.5 + (0.6 * temperature in degrees Celsius).
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
How do you calculate for velocity of sound in air?
The velocity of sound in air can be calculated using the formula: Velocity = frequency x wavelength. The speed of sound in air at room temperature is approximately 343 meters per second.
Scientific notation of velocity of sound?
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
What is velocity of sound in air of conclusion?
The velocity of sound in air can vary depending on factors such as temperature and humidity. On average, at room temperature (20°C), the speed of sound in air is around 343 meters per second. However, this value can change with different conditions.
What is the increase in the velocity of sound in the air for 1 degree Celsius rise in temperature?
The increase in the velocity of sound in air for a 1-degree Celsius rise in temperature is approximately 0.6 m/s. This increase occurs because the speed of sound in air is directly proportional to the square root of the temperature.
Why does the speed of sound depend on the air tenperature?
It is all about the nature. Temperature causes the sound speed.
When the temperature of the air is 25centermeter the velocity of a sound waves traveling?
rarefactionoccurs only in-wave
When the air temperature is 25C what is the velocity of sound waves traveling through the air?
The velocity of sound waves in air at 25°C is approximately 346 meters per second. Sound travels faster in warmer air due to the higher average speed of air molecules.
What is the approximate velocity of the sound in air?
the velocity of sound in the air is 300m/s
When temperature of the air is 25 degrees celsius the velocity of a sound wave traveling through the air is approximately?
At 25 degrees Celsius, the velocity of a sound wave traveling through air is about 346 meters per second. Sound velocity in air increases with temperature due to the increase in air molecule energy.
