when the temperature of the air is 25 degrees Celsius, the velocity of a sound wave traveling through the air is approx.

The approximate speed of sound in air at 25°C is 346.45 m/s².
The velocity of sound in the air is about 330 m/s. The velocity of sound in a liquid is about three times that. But varies widely with liquid. The velocity of sound in a solid body is about 4 or 5 times that of the sound in air. But once again, it varies widely with the solid. hint, check the values for lead and tungsten.
By changing
Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
At 25 Deg C, the speed of sound is 756 MPH. The standard measurement for the "speed of sound" is 20 Deg C, in which sound travels at 768 MPH.
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
I think there is no relation between sound and temperature. But velocity of sound is found to be proportional to the square root of temperature of the medium (air)
The velocity of sound in air is independent of change of the atmospheric pressure, but is really dependent on the temperature.
Velocity, temperature and pressure.
At 25o C, the speed of sound in air, in a standard atmosphere, is about 774 mph.For more details and formula for calculation, see Related links below.
