Using a vacuum chamber is a valid approach because it isolates it from the environment. This helps to control the experiment and prevent other variables from impacting the reaction. In a vacuum chamber, heat transfer occurs primarily through radiation, giving a more accurate measurement of energy. However, it might not completely eliminate electromagnetic fields or thermal radiation and that could possibly interfere with the experiment.

Question

Paraphrase this, make it more understandable

Answer 1

Using a vacuum chamber is a good idea because it keeps the experiment isolated from outside influences. This helps ensure that only the desired variables are affecting the reaction. In a vacuum chamber, heat is mainly transferred through radiation, making it easier to measure energy accurately. However, it may not completely eliminate electromagnetic fields or thermal radiation, which could potentially disrupt the experiment.
