Answer

Brief Explanations:

In thermochemistry, a calorimeter is used to measure heat changes (enthalpy changes) in reactions. But for some reactions, it's not feasible to use a calorimeter due to various reasons like extreme conditions or side - reactions interfering with accurate measurement.

Answer:

calorimeter
