Answer: Temperature = 255K
Explanation: Given that the speed of sound through air is measure to be 319m/s
Speed of sound is proportional to the square root of temperature. That is
V = √ RT/M
Therefore,
V1/V2 = √ T1/T2
The speed of sound in room temperature air is 346 meters per second.
room temperature is taken to be about 20 to 25 degrees Celsius with an average of 23 °C or 300 K is often used.
346/319 = √ 300/T2
1.085 = √ 300/T2
300/T2 = 1.176
T2 = 300/1.176
T2 = 255K
