Meniscus is the shape of the surface of a liquid in a cylindrical container. It may be concave, convex or plane. For molten metals
Correct answer: A. meniscus is concave
- A. meniscus is concave
- B. meniscus is convex
- C. meniscus is plane
- D. meniscus may be concave or convex depending on the nature of the metal
Explanation
In a cylindrical container, the meniscus is the curve observed at the surface of a liquid. The shape of the meniscus depends on the nature of the liquid and its interaction with the container material.For molten metals, the meniscus is typically concave. This is because molten metals often exhibit strong adhesive forces with the container material, causing the liquid to climb up the sides of the container, resulting in a concave meniscus.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
