Question

if a test sample burns fully in a calorimetry experiment, what has it reached? complete degradation reversible degradation partial degradation measurable degradation

Explanation:

In a calorimetry experiment, when a test sample burns fully, it means there is no remaining un - burned material. Complete degradation implies that the sample has been broken down entirely. Reversible degradation would mean the process can be reversed (not the case in burning). Partial degradation means only part is broken down (but the sample burns fully). Measurable degradation just implies the degradation can be measured (but doesn't address the 'fully' aspect).

Answer:

complete degradation
