For diatomic gases like nitrogen and oxygen that are the dominant constituents of air, γ = 1.2. What is the speed of sound at temperature 30.3°C (m/s)? (Hint: the composition of air can be viewed as 80% nitrogen and 20% oxygen, and you should know their mass.)
The sound speed = (γP/ρ)0.5, where P is the gas pressure, ρ is the gas density.
you do hot have a thermometer to measure temp you are able to measures the speed of sound through the air. if you measure the sound to be 349m/s. what is the air temp?
V=331.4m/s + (0.606m/s/1°C)T
apply this formula and answer with the exact value
