热学部分主要讲述分子动理论、气体的状态参量和热力学定律,复习的重点在于对分子体积、质量、数目、平均距离的估算,对布朗运动现象实质的理解,对分子力特点、模型及宏观体现、内能概念的掌握及估算,对热力学第一、二定律、参量守恒定律的理解和计算以及对气体三个状态能量的微量认识等. The thermal part mainly deals with the theory of molecular dynamics, the state parameters of gases, and the law of thermodynamics. The review focuses on the estimation of molecular volume, mass, number, and average distance, the understanding of the essence of Brownian motion phenomena, and the characteristics, models, and macroscopic manifestations of molecular forces. The understanding and calculation of the concept of internal energy, the understanding and calculation of the first and second laws of thermodynamics, the law of conservation of the parameters, and the understanding of the three states of energy of gas.
