SUMMARY
The speed of sound in air can be calculated using the formula \( v = \sqrt{\frac{B}{\rho}} \), where \( B \) is the bulk modulus (1.42 × 105 N/m2) and \( \rho \) is the density (1.211 kg/m3), resulting in a speed of sound of 342.43 m/s. To find the temperature of the air sample, the correct formula is \( v = \sqrt{\frac{1.4 \cdot R \cdot T}{M}} \), where \( R \) is the specific gas constant for air, and \( M \) is the molar mass of air. The user encountered difficulties in calculating the temperature, indicating a potential misunderstanding of the required absolute temperature values.
