Answer
The stirrer distributes heat evenly throughout the water in the calorimeter, ensuring consistent temperature readings.
Moreover, the insulation of the calorimeter minimizes heat loss to the environment, allowing for a more accurate measurement of the heat transferred to the water.

Answer
Water has a high specific heat capacity, meaning it requires a significant amount of heat energy to change its temperature. This property enables accurate measurement since small amounts of heat from the biomass will result in a noticeable temperature change.
