Speed of sound v in an ideal gas : is proportional to the square root of absolute temperature T.
       
         v₂ / v₁ = √(T₂ / T₁)
         664 / 332 = √ (T₂ / 273.15)
         T₂ = 4 * 273.15 °K  = 1092.6°K
         T₂ = 1092.6°K - 273.15  =  819.45 °C

===========================
v=\sqrt{\frac{\gamma\
R\ T}{M}}=\sqrt{\frac{\gamma\ P}{\rho}}=\sqrt{\frac{\gamma\ k_B\ T}{m}}

        γ = ratio of specific heats
         T = absolute temperature
         R universal gas constant.
         M = molar mass of the gas.
         k_B = Boltzmann's constant
         m = mass of a molecule of gas.
