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

Sound travels at a much slower speed than light, causing a delay between seeing the flash and hearing the thunder.

The speed of sound in a medium depends on the properties of the medium, such as temperature and state.

We may perceive one sound as louder than another of equal intensity because our ears may detect it better.

No, while often used interchangeably, loudness and intensity are not the same. Loudness is a measure of the ear’s response to sound.
