理想气体的定义一直以来是一个有争议的问题,其争议的焦点是U=U(T)(即焦耳定律)是不是独立于理想气体状态方程.文章分析了理想气体状态方程与焦尔定律的关系,认为焦尔定律不是完全独立于理想气体状态方程的,焦尔定律与理想气体状态方程是不等价的.从而得出理想气体的科学定义:严格遵守理想气体状态方程PV=nRT的气体,就是理想气体.Abstract :The definition of "ideal gas"is a disputed question , for whether the equation of state (Joul's law )is self exist .The form of definition of ideal g as is discussed .Three ways of deduction of equation state
are discussed in this article
