摘　　要：气体在绝热的密闭容器中自由膨胀 ,体积不断增大 ,从而导致体系的温度、内能、焓等状态函数相应发生改变 ,对于不同的气体 ,这些变化也相应不同 论文分别对理想气体、范氏气体、满足方程P(νm -b)=RT 的实际气体。The volume of the transferred gas will be amplified because the gas conducts, a process of free expansion in a container which insulates from heat Because of this the internal energy enthalpy and so on will change as temperature changes To different gas, the reaction will be different Following is my discussion on imaginal gas, van der waals gas, and so on

关 键 词：气体 绝热 自由膨胀 内能 温度变化
