I know my subject matter well, although you dont. 640mph? sound Barrier is at 640mph?

No 660 is least it will be, Hotter = lower speed of sound, around 11 000 to       20 000meters on a bright and sunny day speed of sound can be 660mph.


sorry got pictures but wont show up, Me 262 at Mach 1.24

At sea level a plane must exceed 741 mph to break the sound barrier

Yes, but we can get to 11 000meters and break it at 660mph

The speed varies depending on atmospheric conditions; the most important factor is the temperature. Air pressure(thus alt.) has almost no effect on sound speed.

Pressure decreases with temperature since atmosphere is open.

The pressure has nothing to do with it, it's the temp that effects it, so you could be at 11,000 meters but it doesn't matter, the temp is all that matters

Actually sound travels slower when atoms are spread out, so less pressure means atoms are farther aprt, thus sound takes longer to travel.
Sound is a vibration and must be transfered by matter, if matter is farther apart it takes longer to go from 1 point to another.
 I didnt know paying attention in science would pay off, it still hasnt but it helped me with this.:aok

Ok I'll try and explain it to you one more time, Air pressure has almost no effect on sound speed.  Sound usually travels more slowly with greater altitude, due to reduced temperature not air pressure.  Read up on the subject.

Ok, well Temperature affects pressure so you know, more heat=less pressure (cuz particles spread out).

Ok but its not the pressure effecting the speed, its the temp, look at it this way, if I took a room to measure the speed of sound in where I could control both pressure and temp in, If I change he pressure in that but left the temp the same the speed would remain almost the same no matter what pressure I set it at, now if I change the temp in that room the speed would change greatly depending on what temp I change it too.

Even then it will vary with moisture and temperature.  Not only is it impossible to say "speed of sound is X at all altitudes," it's not even possible to say "speed of sound is X at Y altitude."  Now if you try, "speed of sound is X at Y altitude with Z humidity and V temperature," then you're starting to make more sense.  And there are still other factors, most likely.

Oldtard, science doesn't say that a bumblebee can't fly.  Bad science does.  It's the same sort of bad science which says that mass and energy can come out of nothing, or that the earth is flat.

Yeah I didnt mention on there that the speed was based on a temp of about 65F.

ok, trax, can you tell me why sound goes faster or slower whith change in temperature?
NO LONG AND COMPLICATED EQUATIONS PLEASE!!!
