Capillary Action Experiment Diagram - Physics Education Resource #23275 (License: Personal Use)

This scientific illustration depicts capillary action: a narrow glass tube (labeled x) is partially submerged in a liquid reservoir (y), causing the liquid to rise inside the tube to a height h above the external meniscus (z), demonstrating intermolecular forces and surface tension effects. The labels clarify key components for educational use in physics or chemistry curricula.

Used in educational web pages, textbooks, or lecture slides explaining fluid dynamics, surface tension, or adhesion/cohesion principles; targets students and educators seeking visual reinforcement of capillary theory.
