Consider calibrating a calorimeter and measuring heat transferred. A sample of compound was
burned in a calorimeter and a temperature change of 3.33°C recorded. When a 1.23 A current
from a 12.0 V source was passed through a heater in the same calorimeter for 156 s, the
temperature changed of 4.47°C was recorded.
3.2.1
Calculate the heat supplied by the heater.
3.2.2
Calculate the calorimeter constant.
