Q

Calibration Factor (theory)

A

Joules/Kilojoules of energy required to raise the temperature of the calorimeter by one degree

(measured in J °C-1 or kJ °C-1)

Q

Finding the Calibration Factor

A

a known amount of energy will be delivered to the water, and the rise in temperature will be recorded

Q

Will the energy content metabolized by the body be equal to the energy content released through combustion

A

No:
- not all components of food that undergo combustion e.g. cellulose can be digested by the body - therefore less energy would be available
- also - not all food ingested (that could be digested) is actually digested - so it will provided less energy than in a calorimeter
