Edexcel IAL Chemistry AS 6.8 Evaluating calorimetry experiments
Extrapolate the cooling line to mixing time, compare measured and accepted enthalpies and link the direction of error to a named heat-transfer or reaction limitation.
How this is tested
- Extrapolate a cooling curve to determine the corrected maximum temperature change.
- Explain why heat loss or incomplete combustion makes measured values less exothermic.
- Evaluate insulation, apparatus, uncertainty and assumptions with directional effects.
