化学热力学中的温度问题

Discussion About Temperature in Chemical Thermodynamics

本文对温度的热力学定义进行阐述 ,并从分子水平上的能量传递观点对热力学体系的宏观性质“温度”进行微观本质解释。说明温度对热力学体系中各种状态函数 :U·H·S·G以及标准平衡常数K 的影响 ,从而得出温度 (T)

This article expounds the Chemical Thermodynamical definition of temperature, though temperature is one of the macrocosmic properties of the thermodynamical system, this article illustrates its microcosmic essence of the view of energy transfer of molecule on the view of energy transfer on molecule level. It guides how temperature influences the state function of the thermodynamic system, such as Internal energy(U),enthalpy(H),entropy(s),Gibbsfrcc energy and standard equilibrium constant of the reaction(K),etc. We Drarw the conclusion that temperature(T)is an important state function of the thermodynamic system.
