Why is it essential for a calorimetry to be an insulated (closed) system? A. The heat exchange must originate from only the reaction (system).

B. Thermal insulation minimizes energy loses to the atmosphere.

C. A and B

D. None of the Above

B.Thermal insulation minimizes energy loses to the atmosphere.

Explanation:

It is important because it helps to stop hit from transferring from the calorimeter to the environment. This would help to have an accurate measurement of the heat that was used in the chemical process. The greatest cause of error that happens in calorimetry is when heat is lost to the environment. To reduce this, you insulate the calorimeter and add a cover.
