I'm not 100% possitive but I'm pretty sure it has to do with the change in the density of the air do to temp.  Thats density not pressure.

Density and pressure are much alike, both are related to the spacing between the particles of an object, Density decreases with higher heat, as does pressure,oh yeah, what does a Barometer measure? AIR PRESSURE, not air density, so yeah, we both are right, Temperature and Pressure are both factors in the speed of sound. Higher pressure and lower temperature go together to make a high speed of sound. Opposite is true for high speed of sound.

Umm sorry to say but your wrong there, density of something has nothing to do with pressure, I'll give you an example.  Say I take a cup of water and put a 100 lb of pressure on it, that wont change it's density, now if I take that same cup of water and apply heat or cold to it it's density will change.

Exaxctly, the same for pressure, but we dont measure air density, we measure AIR PRESSURE. lol, only gotta wait 4 min for a reply!
Do you play in main arena? trax? or H2H arena?

Ok right, but that air pressure has almost no effect on the speed of sound, now the air density does, and it's temp that changes air density, so do you see what I'm saying now

I know exactly what you mean, I would agree with you completely if you quit using density and said pressure.

Density and pressure are two separate things.  They are not the same thing.  Like I said density is effected by temp and has nothing to do with pressure.

I have no idea what u675 is.  I'm guessing its a u-boat.

ok, nevermind, just wondering if anyone knew. Well, this started as a discussion on if you could break sound barrier in 163 and now it about Density of air and barometers, i dont care, its fun discussing stuff!

yep, well ill just go with density then, maybe im wrong, maybe we both are, the thing is we are too lazy to do research and lets not quit being lazy now!

As I stated previously, I'm somewhat "phyiscally challenged" (physically as in physics, not physique - though I be count as challenged in the latter also).  But why would putting pressure on something not change density?  If I put enough pressure on, say, a planet to compress it into the size of a golf ball, wouldn't I have a really, really dense planet?  Or, let's try a star.

Ok, Liquid and Air are both fluids, if we get a bag of fluid(Helium) and compress(as they would so alot of air will fit inside a scuba tank) it will become denser.
