Given: T1 = 27 °C = 27 + 273 = 300 K,

v1 = 340 m/s,

T2 = 127 °C = 127 + 273 = 400 K

To find: Velocity (v2)

Formula: \(\frac{v_1}{v_2}=\sqrt{\frac{T_1}{T_2}}\)

Calculation: From formula,

v2 = v1 \(\sqrt{\frac{T_2}{T_1}}\) = 340, \(\sqrt{\frac{400}{300}}\)

= 340 × 1.1547

∴ v2 = 392.6 m/s

Find the temperature at which the velocity of sound in air will be 1.5 times its velocity at 0 °C

Given: \(\frac{p}{p_0}\) = 1.5, T0 = 0 °C = 273 K To find: Temperature (T) Formula: \(\frac{v}{v_0}=\sqrt{\frac{T}{T_0}}\) Calculation: From formula, \(\frac{T}{T_0}=(\frac{v}{v_0})^2\) ∴ T = T0 \((\frac{v}{v_0})^2\) ∴ T = 273 (1.5)2 = 614.25 K = 341.25 °C
