Effect of temperature on the speed of sound

About Effect of temperature on the speed of sound

Sound travels faster as the temperature of the medium increases and vice-versa. This happens because as temperature increases, the particles of the medium collide more frequently and hence the disturbance spreads faster.

Speed of sound in air increases by 0.61 m/s with every 1°C increase in temperature.

e.g. If speed of sound in air at 0°C is 330 m/s, then its speed at 25°C will be 345 m/s.

Speed of sound does not depends on the pressure of the medium if temperature of the medium remains constant.
