Question

Calculate Medium fine steel wool has a strand diameter of 0.002 inch. If 100 g of this steel wool were burned, what mass of iron oxide would you expect to be produced?

Answer 1

Use this formula

The velocity of sound in air is given by

Cs = √(γRT/M)

where γ is the degree of freedom

T = temperature

M = mass

According to the kinetic theory of gases, The rms velocity of sound is given by

C = √(3RT/M)

dividing both the equation we get

Cs/C = √γ/3

=> Cs = C√(γ/3)

Hence the required relation between the speed of sound in air and rms speed is Cs = C√(γ/3)
