1. The problem statement, all variables and given/known data okay, so what i've been asked to do is explain why a liquid reaches a higher altitude in a skinnier test tube than in a wider test tube. i've brainstormed ideas...but i can't find the one that deals with pressure and tension and stuff like that...stuff that deals with bernoulli's equation. these are my ideas. -capillary action inside the tubes that allows the water to easily climb up walls on a thinner tube than a thicker one. -the weight of the water has to be equal to the atmospheric pressure outside the tube to balance it out. so the thinner the tube, the less water it has in a specific area than a larger tube does in that same area. so water rises more in a thinner tube (to increase the weight) so that the atmospheric pressure outside is equivalent to the pressure inside. -then i was thinking. the area of a thinner tube is less than the area of a thicker tube. so if the area is smaller that means that the pressure is larger. and if the pressure is larger in a skinnier tube, it travels upwards to even out with the lower atmospheric pressure. (at high altitudes, the atmospheric pressure is lower) can anyone help?
