330 m/s approx
Explanation:
The RMS speed of a gas is proportional to square root of its absolute temperature is
V ( RMS ) ∝ √T
Here V₁ = 200 , T₁ = 23 +273 = 300K , T₂ = 227 +273 = 500 K
Putting the values
200 / V₂ =
V₂ = 330 m/s approx
The speed of sound, c, is given by the Newton-Laplace formula
where
K = bulk modulus
ρ = density
Because the density is constant, the speed of sound is proportional to the square root of the bulk modulus.
Therefore when the bulk modulus increases, the speed of sound increases by the square root of the bulk modulus.
For example, if K is doubled, then
Answer:
If the bulk modulus increases by a factor of n, then c increases by a factor of √n.
