Changes in heat cannot be measured directly but are calculated using temperature differences. Often calorimetry is used to collect this data. Why is a calorimeter utilized?
A: A calorimeter allows temperature differences to be measured, which otherwise could not be determined.
B: A calorimeter enables scientists to isolate the system that is being studied as well as minimize the amount of heat transfer between the system and the surroundings.
