Actually I believe that the main reason for the "heating of the air" is the
compression itself (anisothermal?/anisobaric? - what's the word I'm looking
for here guys?).  Anyway, taking 1 cubic foot of air at some temperature
and
squishing it down to half a cubic foot (say) approx. doubles the
temperature
of that air (the same thermal energy has to reside in half the space).
