高中一年级第六章分子运动论热和功一、概述本章在原教材中为上册第八章,与原教材比较,只是删去了原教材练习四的第(2)题和习题的第(4)题,这两道计算题都涉及热功当量的数值,现在,按国际单位制,热量和功的单位统一用焦耳,一般不再用卡为热量单位,没有必要强化热功当量的具体数值。本章内容包括两部分,一、三节介绍分子运动论、统计规律等统计力学的一些粗浅知识,四、七节介绍内能、功、热量概念和能的转化和守恒定律等热力学的一些初步知识,这些知识虽然是初步
The sixth chapter of the senior high school and the first chapter of the molecular movement theory are summarized in Chapter 8 of the previous volume. Compared with the original textbooks, this chapter only deletes the (2) and exercises (4) of the original exercises. The two calculation questions are related to the value of the thermal work equivalent. Now, according to the international system of units, the units of heat and work are used in Joules. Generally, cards are no longer used as heat units, and there is no need to increase the specific value of heat work equivalents. . This chapter includes two parts. Sections 1 and 3 introduce some superficial knowledge of molecular mechanics, statistical laws and other statistical mechanics. Sections 4 and 7 introduce some preliminary knowledge of thermodynamics such as internal energy, work, heat concept and energy conversion and conservation laws. Although these knowledge are preliminary
