It provides a way to test a hypothesis
Capillary action<span> occurs when the adhesion to the walls is stronger than the cohesive </span>forces<span> between the liquid molecules. The </span>height to which capillary action will take water<span> in a uniform circular </span>tube<span> is limited by surface tension and, of course, gravity.</span>

P1T2 = P2T1
(3.8)(36)=25P2
136.8=25P2
136.8/25=P2
P2=5.472atm
