在普通物理实验研究水的沸点和压强关系时,一般只讨论低于1大气压的沸点和压强的关系,而对于1大气压以上沸点压强关系,由于没有相应的实验设备,不能做这方面的实验,学生得到的知识是片面的、不完整的。为此,我们在水的沸点压强关系测定的实验中,补充了高压下水的沸点压强关系测定的内容,本文将介绍有关的实验装置和实验方法。
In the general physical experiment to study the relation between the boiling point and the pressure of water, only the relationship between the boiling point and the pressure below 1 atm is generally discussed. For the relationship between the boiling point and the pressure above 1 atm, since there is no corresponding experimental equipment, Students get the knowledge is one-sided, incomplete. For this reason, we added the determination of the relationship between the boiling point and the pressure of the water under high pressure in the experiment of measuring the relationship between the boiling point and the boiling point of water. This article will introduce the relevant experimental devices and experimental methods.
