Subject: On temperature
But if . . . they had to be
accelerated by the walls of the container, then all
bets are off! They could not all be accelerated
exactly identically, and thus some increase in their
average random motions would be expected.
Not so, consider a single ball bearing
in the container touching the
back wall. The ball bearing remains against
the back wall the whole
trip and only lifts off the wall with
only a minor relative velocity
(reflecting energy stored in elastic
deformation of the bearing while
accelerated) after acceleration ends.
Your assumption (which Ben recognized
without investigating it) is not based
on the reality of gasses: the molecules
are bouncing off the walls all the
time during acceleration. It should
be verified if as much energy will be
transferred to the gas as to the
container, per unit of mass (probably
papers on that topic exist). However,
probably it's not really important for
what you wanted to ask: you could just
state your question as neglecting
eventual residual effects from
acceleration on the local meaurement of
temperature.

Harry! Where did you come from. You do not have
time answering all these other people's posts. I need
your help with all my crazy posts! What are you doing?
We all know that the speed at which you accelerate
between frames can be important. Take slow motion
sync, with clocks. If you go real slow, you achieve
certain desired results: Clocks are able to reach
a fairly good sync with respect to each other. But
if you accelerate too fast, then clocks become out
of sync! The same is true with temperature. A
slow motion act maitains more the same temperature,
than if you shook the container, etc, with a fast
displacement. So Harry, tell them how we, with
LET, understand all these things! Thanks!

It does.
