I still don't know how to determine the volume 2 for the first question on the 1/24 assignment.
You wrote You can find the volume of water that enters the tube. It's a few cm^3, and this water is displaced by the additional volume of air in the tube.

Careless editing on my part. That should read
'You can find the volume of water that enters the tube. It's a few cm^3, and this water is displaced by the additional volume of air in the bottle.'
Note the change in the last word of the statement.*@
You know V1, so you can find V2 by adding the added volume to the previous volume.
T1 is again 300 K. So you know P1 (1 atm or 100 000 Pa), V1 and T1. You know P2 (still 106 000 Pa) and V2. So you can find T2.*@
But I cannot find where there's a change in height of the air column. Am I missing something?
Having the preceding correction, you probably won't need the following, but just in case:
The premise behind this problem is that water is raised in the tube to a height of 60 cm. It was that height on which the pressure change (approximately 6000 Pa) was based, and the 318 K temperature was calculated.
