Hi I'm not sure. I was given this problem in a practice. Maybe assuming there's an unknown gas inside? Situation 2 might be held by the atmospheric pressure? I have to find out the exact length covered by mercury.. Help!

Hi do you mean this? I need to know exactly what are the lengths for both specific situation...

The problem statement Recently I came across this problem and couldn't understand it. I know that in situation 1, the length of the specific place will be decreased; In situation 2, it will be increased. Can someone help me here? Thanks first!
