At what temperatu

Answer :


Initial temperature of air = 0° C = 273.15 K

We know that the speed of sound in air is given by the equation,

where γ is the ratio of specific heat at constant pressure to specific heat at constant volume for air, R is the universal gas constant, T is temperature and M is the mass of the gas. Keeping everything constant except temperature,

Let the velocity of sound in air at 0° C be v0 and the velocity at temperature T be vt, then

When vt=3v0
