Different proof methods of Dalton's partial volume law equivalent to Dalton's partial pressure law

Abstract

As we all know, Dalton's law of the partial pressure is equivalent to Dalton's law of the partial volume. On the other hand, through experiments, it can be proved that Dalton's law of the partial volume is correct, and Dalton's law of the partial pressure can be derived from Dalton's law of the partial volume, implying that both laws are equivalent to each other. Combined with the teaching of middle school physics and university basic physics, with different ideas and methods, this paper presents a variety of proof methods of Dalton's law of the partial volume to be equivalent to Dalton's law of the partial pressure. Different proof methods can improve the understanding and application of Dalton's law of the partial pressure and law of the partial volume. It is proved that the relevant content of Dalton's ideal gas partial pressure law is further supplemented and perfected, which plays a role throwing some light on this field.
