Sound bounces off a solid or liquid surface, similar to how a rubber ball bounces off a wall.

The speed of sound varies at different temperatures within a medium, increasing as temperature rises due to increased molecular motion.

Yes, in air, the speed of sound is 331 m/s at 0°C and 344 m/s at 22°C.

Increasing the temperature of a medium generally increases the speed of sound.

The speed of sound decreases as we transition from a solid to a gaseous state.
