The curved surface of a liquid in a measuring device used to read accurate dosage is called the

• A. Curve
• B. Meniscus
• C. Reading
• D. Volume

Answer: (B)

The curved surface is called the meniscus. It forms because the liquid’s molecules are attracted to the container (adhesion) and to each other (cohesion). In most dosage devices with glass, this pulls the liquid up along the sides, making a concave curve with the lowest point in the center. Read the measurement at the bottom of that curve, at eye level, to avoid parallax and get an accurate dose. The other terms don’t describe the surface itself or the act of reading a measurement, so they’re not the correct name here.
