Surface Tension — Syllabus & Topics
Topics covered in Surface Tension for NEET-UG Physics.
Topics in Surface Tension
Intermolecular Forces and Basic Concepts
- Intermolecular forces are electromagnetic in nature with range ~10⁻⁹ m
- Cohesive force acts between molecules of same substance (mercury drops coalescing)
- Adhesive force acts between molecules of different substances (chalk on blackboard)
Surface Tension - Definition and Properties
- Surface tension causes liquid surface to behave like stretched elastic membrane
- Measured as force per unit length acting perpendicular to imaginary line on liquid surface
- Scalar quantity with unique direction (tangential to surface)
Forces Due to Surface Tension
- Different geometries require different force calculations
- Hollow disc and thin ring have different contact lengths
- Square frame has 8 edges in contact with liquid
Molecular Theory and Surface Energy
- Molecules in bulk liquid have zero net force (equal attraction from all sides)
- Surface molecules experience net downward force due to asymmetric environment
- Work must be done to bring molecule from bulk to surface
