The word "and" has a short A sound, as in band and sand. The long A is heard in words such as pain and paid.
Onomatopoeia is a sound word. For example, bam and boom are not names, but is used to describe sound.

The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room; see link: "Speed of Sound in Air and the effective Temperature".
No, both words sound like they could be examples, however, the sound of both words are extinct from their original word. An example of onomatopoeia would be ding-dong since it represents a sound of a bell.
