Laplace pointed out that compressions and rarefactions occur so rapidly that heat generated cannot be dissipated sufficiently rapidly.; so the conditions confirm to Adiabatic changes and Not to isothermal changes
pvy = constant
pyvy-1 dv + vydp =0
Put bulk modulus B = - dP/(dV/v)=γP( from above equation)
Then the speed of sound
finally,v = squareroot of γp/D
γ= ratio of specific heats
D =density of the medium
