Elasticity
Why a rubber band springs back, chewing gum stays stretched, and engineers trust Young's modulus.
What this unit covers
Unit 6: Properties of Matter and Heat
- 1 ElasticityWhy a rubber band springs back, chewing gum stays stretched, and engineers trust Young's modulus. · 10 min
- 2 Pressure in FluidsWhy a needle pierces skin, a drip bag hangs high, and blood pressure is still quoted in millimetres of mercury. · 10 min
- 3 Pascal's Principle, Archimedes' Principle, Surface Tension and ViscosityA small push becomes a huge lift, a steel ship floats, and water climbs up thin tubes all by itself. · 14 min
- 4 Temperature, Thermometry and Thermal ExpansionThree temperature scales, the clever kink in a clinical thermometer, and why railway lines need gaps. · 14 min
- 5 Specific Heat Capacity and Latent HeatWhy a pot of water takes so long to boil, and why boiling it dry takes five times longer still. · 10 min
- 6 Heat TransferConduction, convection and radiation, the sea breeze in Lagos, and the flask that keeps tea hot all day. · 13 min
