Study Plan
Learn the Theory
Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Molecular Theory of Matter and Intermolecular Forces, Elasticity, Elastic and Plastic Bodies, Stress — Definition, Types and Formula.
Practise
Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.
Revise & Test
Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.
Spaced Revision

What to Focus On
- Equilibrium separation R₀ is the distance at which the net intermolecular force is zero.
- For R > R₀: Attractive intermolecular forces act between molecules.
- For R < R₀: Repulsive intermolecular forces act between molecules.
- Elasticity is the property of matter to regain original shape and size after removal of deforming force.
- Perfectly elastic bodies completely recover — quartz fibre is the closest real example.
- Perfectly plastic bodies do not recover at all — ordinary putty is the closest real example.
- Stress = Restoring Force / Area = F/A
- Unit of stress: N m⁻² or Pascal (Pa)
- Stress is a scalar quantity but it has direction-dependent nature (type depends on force direction).
Common Mistakes to Avoid
Rubber is more elastic than steel because rubber can stretch much more.
Stress and pressure are the same thing since both equal Force/Area.
Hooke's Law applies to all materials under any amount of force.
Memory Tips
Elasticity — property to regain original shape after deforming force is removed
Elastic vs Plastic — Quartz fibre (most elastic) vs Putty (most plastic)
Stress = Force / Area (Internal restoring force per unit area)
Three types of stress: Longitudinal, Normal (Bulk), Shearing
