BOND ENERGY: Energy required to break a bond
sCALORIMETRY EXPERIMENT FOR COMBUSTION:
sCALORIMETRY EXPERIMENT - COMBUSTION |
Diagram showing the Calorimetry Experiment for Combustion |
METHOD:
Using a measuring cylinder, measure 100 cm3 of Water into a Copper Can (Copper provides efficient heat insulation) Measure and record the initial temperature of Water Filling the spirit burner with test substance, measure and record its mass Place the burner under the Copper can and light the wick Constantly stir the Water and continue heating until the spirit burner burns out Measure and record the highest temperature of Water
|
CALCULATION:
Temperature Change of Water = Final Temperature - Initial Temperature

sCALORIMETRY EXPERIMENT FOR DISPLACEMENT, DISSOLVING AND NEUTRALISATION:
sCALORIMETRY EXPERIMENT - DISPLACEMENT, DISSOLVING AND NEUTRALISATION |
Diagram showing the Calorimetry Experiment for Displacement, Dissolving and Neutralisation |
METHOD:
Using a measuring cylinder, measure 25 cm3 of Solution 1 into a Polystyrene cup Measure and record the temperature of Solution 1 Add a measured amount of reactant (solid for dissolving, solution 2 for displacement and neutralisation) into the Polystyrene cup and stir the mixture Measure and record the highest temperature reached by the mixture

CALCULATION:
Temperature Change = Final Temperature - Initial Temperature
