To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched; this aims to foster active technical exchanges while also providing financial rewards to users. 【Daily Question】 (Single-choice question) When performing an absolute calibration of the volume of a burette using the weighing method, the volume value obtained represents the actual capacity of the burette under ( ). A 25℃ B 20℃ C Actual measured temperature D 0℃ Please reply with your answer in the comments; answering correctly earns +2 wealth points, while getting all answers right adds another +3 to +8 wealth points. Those who provide thorough analysis and explanations for the questions or answers (or include detailed calculation processes) will receive additional wealth rewards. If your answer is correct and your analysis is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions. Note: We will close this post after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation.
When performing an absolute calibration of the burette volume using the weighing method, the volume value obtained represents the actual capacity of the burette at (C).
When performing an absolute calibration of the burette volume using the weighing method, the volume value obtained represents the actual capacity of the burette at (B 20°C).

When performing an absolute calibration of the burette volume using the weighing method, the volume value obtained represents the actual capacity of the burette at (B 20°C).
The answer is C, the actual measured temperature. Right?:)
