UPSC NDA-2 – 2022
– The speed of sound in steel is higher than in water, and the speed of sound in water is higher than in air.
– The speed of sound in a gas (like air) increases with increasing temperature. As temperature rises, the average kinetic energy of the gas molecules increases, and they collide more frequently and vigorously, allowing the sound wave to travel faster.
