Question

I did a lab on pressure and depth today. This lab was to simply submerge a plastic tube into a large graduated cynlinder to find the relationship between the two. I found that as the depth increases, so does the pressure. One of the questions I'm stuck on for part of my lab report is this one:
On a molecular level, describe why you think this is happening.

Answer 1

As the depth increases, there are more molecules on top pressing down.

Answer 2

Thank you!
What would be the difference if a small graduated cylinder was used instead of a large one? The pressure would still increase as the depth increases? What about the molecules?

Answer 3

hey! i've been waiting for my question to be answered. if of you have another question, please post a new question.
