well sometimes it's appropriate. obviously depending on who you are talking to, but for the bulk of non nerds simpler is better. like this "Temperature is also vitally important, depending on the gaseous element, or molecular compound that you wish to consider, in this science"Arrggh...too many years since a CFI, now can't help myself, and over-explain, over-complicate
is total gobbley gook. "when its cold enough it freezes" (what "it" is doesn't matter)

ah. not only did I understand that. I actually read it.Or maybe
"Air behaves like a fluid, it flows around an object like water does, leaving a swirling wake a bit like a boat does. Most of the time you can't see it, but if it's damp out the wake is sometimes visible, like in these examples...".
