Description

[概要]近代化学の父といわれているラヴォアジエが質量保存の法則を発見した。この法則を確認する実験に関しては、義務教育課程の教科書に種々の方法が提案されている。ここでは、大勢の受講生を対象に安全で精度よく確認できる方法であり、化学量論や化学反応熱などの法則も合わせて確認できる実験法を開発した。さらに、この実験法では理想気体の状態方程式の理解を促すことができる。 Lavoisier called modern chemical father discovered the law of conservation of mass. The experimental methods were written in the textbook of the compulsory education process in elementary and junior high school, to checks the law. In this paper, a new experimental method was proposed for students experiment. It is important to satisfy with safely and sufficient accuracy for large number of attendance student in a classroom. Moreover, some fundamental laws, such as the stoichiometry and enthalpies and reaction rate of chemical reaction, can also be united and checked. Furthermore, a gas state equation may be adapted for higher applications.
