气体常数(又称通用或理想气体常数,通常用符号R表示)是一个在物态方程中联系各个热力学函数的物理常数。(气体常数与阿伏伽德罗常数的比为波尔兹曼常数。)这是表征理想气体性质的一个常数。 气体常数相当于玻尔兹曼常数,但以每摩尔每温度增量(而不是每个颗粒每温度增量的能量)表示为能量单位(即压力 - 体积积)。常数也是Boyle定律,Charles法,Avogadro定律和Gay-Lussac定律的常数组合。 气体常数值是8.314J/(mol·K)。

否则,气体常数值,绝热指数值无法确定,后续计算也无法进行。
Otherwise, the value R of the gas constant and value K of adiabatic exponent can not be determined and the subsequent calculation also can not be conducted.
It only cares what temperature is. If temperature is constant, there's no change in energy.
如果温度是常数,能量就没有变化,对理想气体。
R They're related through the gas constant.
理想气体常数。
The ideal gas constant doesn't change, temperature doesn't change, and so v we just have minus nRT integral V1, V2, dV over V.
理想气体常数不变,温度也不变,因此,是负的nRT,积分从v1到v2,dv除以。
