Question

what is the Newton's formula for the speed of sound in gases?​

Answer 1

Answer:

v =root B upon p

v for velocity

B for bulk modulus

and p for density

Answer 2

Answer:

The speed of sound in an ideal gas is given by the relationship

v(sound)= under root yRT/M

R = the universal gas constant = 8.314 J/mol K,

T = the absolute temperature

M = the molecular weight of the gas in kg/mol

γ = the adiabatic constant, characteristic of the specific gas

For air, the adiabatic constant γ = 1.4 and the average molecular mass for dry air is 28.95 gm/mol. This leads to

V(sound)

= under root 1.4(8.314J/ mol.K) /0.02895kg/mol × under root T

= 20.05 under root T m/s
