摘要

反應熱的求取，常利用簡易的卡計來測定。本文討論利用隔熱效果好的保溫杯，刻度至0.1℃的溫度計，50毫升的滴定管，再加上正確的數據處理法，來改進卡計的測量法，以提高卡計法的精密度，減少實驗的誤差。

In general chemistry laboratories, heat of reaction is generally measured by using a simple calorimeter. In order to obtain acceptable accuracy and precision, it is critical to use proper apparatus and proper quantities of reagents. According to the procedure usually suggested, the thermometer must be readable to 0.03℃; the volume must be 0.03 ml; the concentrations of acid and base must be standardized to 1.00 M; and the weight of ice must be g. about 10.00g.
