Question

The velocity of sound in air being 332 ms-1 at 0°C. Find the change in velocity per degree rise in temperature.​

Answer 1

The change in velocity of sound per degree Celsius can be calculated using the formula:

Δv/ΔT = 0.6 m/s/°C

Where Δv is the change in velocity and ΔT is the change in temperature.

To find the change in velocity per degree rise in temperature, we substitute the given velocity of sound at 0°C and the temperature change of 1°C:

Δv/ΔT = 0.6 m/s/°C

Δv/1°C = 0.6 m/s/°C

Δv = 0.6 m/s

Therefore, the change in velocity per degree rise in temperature is 0.6 m/s.

Answer 2

I think the velocity of sound in air at 0°C is 332m/s.

Explanation:

It increases by `0.6m//s` for each °Celsius rise in temperature.

The wavelength of sounds= 169Hz at 273+10=283K .

Now, formula becomes

v=nλ

or, where v= velocity, n= frequency, λ= wavelength

⇒λ= nv = 169 332= 1.9 m
