The velocity of sound in air at 27 °C is 340 m/s. Calculate the velocity of sound in air at 127 °C.
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, \(\sqrt{\frac{400}{300}}\) =...
