Sample Problem
The meniscus is the shape of the upper surface of a liquid close to the surface of a container or another object. It may be convex (curved upwards) or concave (curved downwards). Based on your knowledge of IMFs, explain why oil tends to form convex menisci while water forms concave menisci.
Answer: In comparison to oil, water has far greater adhesive properties thanks to its hydrogen bonding, in addition to the smaller molecule size of water which allows for greater interaction with the container.
