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.
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.
