Question

Water can flow out of a straw because of what property.A: solubility B: cohesion C: capillary actionD: adhesion

Answer 1

To answer this question we need to remember some concepts, capillarity is a fluid propriety, that depends on surface tension and this, in turn, is given by the fluid cohesion. This element makes it possible that the liquid flows through a narrow space without assistance, even more against gravity in some cases. So taking this into account we can say that the correct answer is option C.
