Question

differentiate between upper meniscus and lower meniscus

Answer 1

Answer:

A meniscus may be either concave or convex. A concave meniscus curves downward; if you are looking down from the top, it curves away from you, like the opening of a cave would. In contrast, a convex meniscus curves upward; if you are looking down into the container, the meniscus curves toward you.
