What is the effect of temperature on the speed of sound in the air?

The speed of sound in air is significantly influenced by temperature. As the temperature rises, the molecules in the air move faster due to increased kinetic energy, which facilitates quicker transmission of sound waves. This is because sound travels through the vibration of molecules, and at higher temperatures, the increased energy leads to quicker propagation of these vibrations.

Conversely, at lower temperatures, molecular motion is reduced, and sound waves travel more slowly as the air molecules are denser and less energetic. Thus, as conditions become warmer, the sound speed increases, making the assertion that speed increases with temperature correct.

Understanding this relationship is particularly important for pilots and aviation professionals. It impacts flight operations, including takeoff and landing distances, airspeed calculations, and overall flight performance, especially under varying atmospheric conditions.
