“The minimum speed of sound in air at 0°C is roughly:”

"The speed of sound in air at 0°C is approximately 331 meters per second. This value depends on temperature as sound travels faster in warmer air due to increased molecular activity. In scientific terms the speed of sound is influenced by the medium’s density and elasticity. At 0°C air’s molecular structure results in this baseline speed widely used in physics calculations. Understanding this concept is crucial for applications in acoustics meteorology and engineering where sound propagation affects technology and environmental studies."
