摘要
应用改进的绝热自由膨胀实验装置,分析了焦耳系数描述的有效性,按照热力学理论分别计算了几种气体的焦耳系数.理论上预言了各种气体经绝热自由膨胀后温度的变化,并从气体内能和分子力的角度给出了其微观解释.
Improved experimental facility for adiabatic free expansion was adopted to the validity analysis of Joule coefficient description and by use of the thermodynamics theory,the Joule coefficients of a few types of gases are worked out.A theoretic prediction of the temperature change is made of the various gases after having been subjected to an adiabatic free expansion and an interpretation of the temperature change is made from the perspective s of the internal energy and the molecular force of gas.
