Q:
Say I have a can or a tube that holds a vacuum (I know it won't be a perfect vacuum, but whatever the best we achieve in lab today is), then I heat the can or tube up from the outside (say with a flame), would the temperature inside the vacuum rise or stay the same (knowing also that it won't be zero kelvin to begin with)?
