i can reveal something tangential i read that somehow ( amazingly ) people on physics forums were able to grasp ...
namely why Argon is more insulating than Air ... it's because Argon is an atom while Nitrogen is a molecule and a molecule can vibrate while an Atom can't ... so that was an easy one
but when comparing noble gases ( Krypton, Argon, Helium ) they are all single atoms and differ only in weight - so why do the heavier ones insulate ?
that is a question of momentum and kinetic energy and requires a functioning brain to understand ... ok it really requires being me more like ...
this is just an example of the types of problems i like to think about. when designing speakers ( as DIYer ) i had to think a lot about questions like this, namely about how gas transmits energy ...
though i was thinking about acoustical energy and we are talking about thermal energy here ... and more specifically about conduction and not convection or radiation ... those are also factors in window design but not subject of this particular paradox ...
it's also possible my theory is wrong but it's plausible enough that i can put this issue aside and move on with life ...
