4 Concept Maps

Flowchart showing conditions for capillary rise and depression

Flowchart showing conditions for capillary rise and depression

The map in words

  • Capillary Tube Dipped in Liquid
    • Force Analysis
      • Adhesive Force: Pulls Along Wall
        • Acute or Obtuse?
          • Acute Angle: Adhesion > Gravity
            • Capillary Rise
              • Liquid Level UP
          • Obtuse Angle: Cohesion > Adhesion
            • Capillary Depression
              • Liquid Level DOWN
      • Surface Tension: Creates Meniscus
      • Gravity: Pulls Downward

Flowchart showing how molecular imbalance at the liquid surface creates surface tension

Flowchart showing how molecular imbalance at the liquid surface creates surface tension

The map in words

  • Liquid Surface
    • Molecular Forces
      • Unbalanced: Molecules at Surface
        • Pulled Inward
          • Minimum Surface Area
            • Stretched Membrane Effect
              • Surface Tension

Flowchart showing step-by-step derivation of capillary rise formula

Flowchart showing step-by-step derivation of capillary rise formula

The map in words

  • Capillary Tube Analysis
    • Upward Force
      • Surface Tension F_up = 2πrT cos θ
        • Equilibrium
          • 2πrT cos θ = πr²hρg
            • Simplify
              • h = 2T cos θ / rρg
                • Capillary Rise Formula
    • Downward Force
      • Weight of Liquid W = πr²hρg
