Temperature — EVERYTHING You Need to Know | Cambridge 9702 A2 Physics (Temperature)

Temperature & Absolute Zero — EVERYTHING You Need to Know | Cambridge 9702 A2 Physics (Chapter 14) What actually IS temperature, and why does -273°C mark an absolute limit that nothing can go below? This video covers the full Temperature chapter for Cambridge International A Level Physics (9702) Paper 4 — thermal equilibrium, the Kelvin scale, and why absolute zero exists, explained from first principles so it actually makes sense (not just memorized). 📌 WHAT YOU'LL LEARN: ✅ Thermal equilibrium ✅ Temperature scales: Celsius vs. Kelvin, and how to convert between them ✅ Why absolute zero (-273.15°C) is a real physical limit ✅ thermodynamic temperature scales ✅ How thermometers actually work (and their limitations) ✅ Common exam traps examiners love to set — and how to dodge them 🎯 This video covers the full CIE 9702 syllabus point for Temperature (Chapter 14) and is designed for students working toward an A*/full marks in A Level Physics. 📚 More revision videos on the channel — full playlist covering every A2 Physics chapter, linked below. 🔔 Subscribe for the rest of the A2 Physics 9702 series — new chapters uploaded regularly. 💬 Comment your muddiest point on Temperature and I'll pin the best answers. #ALevelPhysics #Cambridge9702 #Temperature #AbsoluteZero #Physics #APhysics #ThermalPhysics #PhysicsRevision #ALevels #KelvinScale #StudyWithMe #ExamRevision
