When the temperature of the air is 50°c, the velocity of a sound wave traveling through the air is approximately

In this item, we are to calculate for the speed or velocity of sound in air with a temperature of 50°C. The dependence of the velocity of sound in temperature is expressed in the following equation:
                        v = 331 m/s + (0.6 m/s°C)(T)
where v is the velocity and T is temperature. 

Substituting the known values from the given,
                        v = 331 + (0.6)(50) = 361 m/s

Thus, the velocity of sound in air at 50°C is approximately 361 m/s.
