Where 30,000 fits
Why 30,000 is special
The rapid expansion of that superheated air is thunder. Light and sound from the same event arrive at different times, which is why counting the gap gives the distance.

Science
A lightning channel reaches around 30,000 K, several times the Sun's surface temperature, for a few millionths of a second. Thunder is the shockwave from air expanding at that temperature.
