PHY 232

Your 'measuring atmospheric pressure' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

** your comment **

** How does the system behave and how does it 'feel'? **

The pressure in the pressure tube goes up slightly the more force is applied to the bottle and the long tube fills with water.

** Length of the air column in units of your measuring device: **

I am using an ordinary ruler

** Your report of the vertical position of the first mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **

The length of the water column is 44cm and there is a 15cm space between the water and the cap at the end.

** Your report of the vertical position of the second mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **

The first column is the height of the water in the vertical tube. The second column is the distance between the end of the water and the stopper at the end of the tube. The third column is the distance of the water past the original unsqueezed mark.

** Your report of the vertical position of the highest mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **
