IB DP Chemistry R1.1 L1 | Energy Transfer: System, Surroundings, Endothermic and Exothermic | Lesson Walkthrough
Use hot and cold reactions to distinguish the system from its surroundings, explain energy conservation, and classify endothermic and exothermic changes.
IB DP Chemistry R1.1 L2 | Energy Profiles, Relative Stability and the Sign of Enthalpy Change | Lesson Walkthrough
Connect thermometer observations, energy-transfer directions and energy profiles. Students practise the sign of enthalpy change, enthalpic stability, graph interpretation and error correction.
IB DP Chemistry R1.1 L3 | Calorimetry Foundations: From Temperature Change to Heat | Lesson Walkthrough
Build Q = mcΔT from scaling arguments, interpret specific heat capacity and practise calorimetry calculations with consistent units. The lesson also introduces standard-state conventions and experimental assumptions.
IB DP Chemistry R1.1 L4 | From Calorimetry Data to Molar Enthalpy Change | Lesson Walkthrough
Convert calorimetry measurements into molar enthalpy changes through neutralisation, dissolution and combustion examples. Students check solution or water mass, reacting moles, energy units and the physical meaning of the sign.
IB DP Chemistry R1.1 L5 | Why Experimental Enthalpy Values Are Often Too Small | Lesson Walkthrough
Evaluate why experimental enthalpy values differ from accepted data. Students analyse heat transfer, apparatus heating, incomplete combustion and evaporation, then use cooling-curve extrapolation and justify practical improvements.
