Interpretation: Possible source of error of the calorie content of a peanut measured by burning needs to be determined.
Concept Introduction: Calorimetry is the science of measuring the energy released or absorbed by a chemical or physical change. In combustion reaction a bomb calorimeter is used to measure the quantity of heat transferred.

Answer to Problem 8E
Option B is correct.
Explanation of Solution
In calorimetry experiment it is very difficult to control heat transfer to the surrounding air and equipment. The number of calories transferred from a substance that burns depends on the identity of the substance and its mass. It is very often to occur errors in temperature measurement, mass measurement and heat loss in calorimetry analysis.
Option A, C, D and E are incorrect.
