Question
**Question:** Meniscus is the interface that is straight because of surface tension and water adhesion on the graduated cylinder. - ○ True - ○ False **Explanation:** In a graduated cylinder, the meniscus is typically not straight. Surface tension and water adhesion cause the liquid to curve, creating either a concave or convex meniscus, depending on the liquid's properties. For water and most liquids, the meniscus is concave due to adhesion to the glass being stronger than the cohesion among water molecules. To read the volume accurately, the measurement should be taken at the lowest point of the meniscus.
