第三单元第三单元讲述气体压强,主要是大气压强。包括教科书第八章中的第八～十一节。第十节气体的压强跟体积的关系是大纲规定的选学内容。 1 大纲规定的教学内容和要求 1.1 教学内容 1.1.1 大气压强演示大气压强的存在、托里拆利实验(挂图)、气压计(实物或挂图)。 1.1.2 (选学)气体压强跟体积的关系演示一定质量的气体体积减小,压强均大;体积增大,压强减小。
The third unit of the third unit describes the gas pressure, mainly atmospheric pressure. Including Sections 8 through 11 of the eighth chapter of the textbook. The relationship between the pressure and volume of the gas in the tenth section is the contents of the syllabus. 1 Outline teaching content and requirements 1.1 Teaching content 1.1.1 Atmospheric pressure demonstrates the presence of atmospheric pressure, Torrice experiment (wall chart), barometer (physical or wall chart). 1.1.2 (Selection) The relationship between gas pressure and volume demonstrates that the volume of a certain volume of gas decreases and the pressure is large; the volume increases and the pressure decreases.
