We’re being asked to calculate the heat capacity of the calorimeter. This is given by the equation:
where qcalorimeter = heat absorbed by the calorimeter and qsolution = heat absorbed by the water in the calorimeter.
Expanding this, we have:
Ccal = heat capacity of the calorimeter
m = mass of water (in grams)
c = specific heat capacity of water
ΔT = change in temperature = final T – initial T.
The combustion of 1 mole of glucose C6H12O6 releases 2.82×103 kJ of heat. If 1.25 g of glucose are burnt in a calorimeter containing 0.95 kg of water and the temperature of the entire system raises from 20.10 °C to 23.25 °C. What is the heat capacity of the calorimeter?
