Here's how to calculate the speed of sound in air at 25°C:

Formula:

The speed of sound in air (v) is calculated using the following formula:

v = 331.4 + 0.606 * T

where:

* v = speed of sound in meters per second (m/s)

* T = temperature in degrees Celsius (°C)

Calculation:

1. Substitute the temperature: T = 25°C

2. Calculate the speed:

v = 331.4 + 0.606 * 25

v = 331.4 + 15.15

v = 346.55 m/s

Therefore, the speed of sound waves traveling through air at 25°C is approximately 346.55 m/s.
