A glass capillary tube is placed in a beaker containing a substance in its liquid state. After an hour the liquid shows no tendency to move up the tube. What is the most likely shape of the meniscus within the tube and why would it have that shape?
1.concave meniscus because the liquid-liquid interactions are weaker than the liquid-glass interactions.
2.concave meniscus because liquid-liquid interactions are stronger than the liquid-glass interactions.
3.convex meniscus because the liquid-liquid interactions are weaker than the liquid-glass interactions.
4.convex meniscus because the liquid-liquid interaction are stronger than the liquid-glass interactions.
