热学是研究与温度有关的热现象的科学,它是从两个方面来研究热现象及规律的:一是从物质的微观结构即分子动理论的观点来解释与揭示热学宏观量及热学规律的本质;二是以观测和实验事实为依据,寻找各热学参量之间的关系及热功转换.目前高考中热学内容包括分子动理论、热力学规律、气体等.分子动理论是物质的微观结构学说,是宏观现象与微观本质间的联系纽带;能的转化与守恒定律是自然界普遍适用的规律.下面分板块结合近几年高考现状及命题趋势进行剖析.
Thermal science is the science of studying thermal phenomena related to temperature. It studies thermal phenomena and laws from two aspects: First, it explains and reveals macroscopic quantities of heat and thermal laws from the viewpoint of the microscopic structure of matter, ie, the theory of molecular dynamics. Essence; Second, based on observations and experimental facts, to find the relationship between the thermal parameters and thermal power conversion. At present, the thermal content of the college entrance examination includes molecular dynamic theory, thermodynamic law, gas, etc. The molecular dynamic theory is the microscopic theory of matter. , is the link between macroscopic phenomena and microscopic nature; the law of energy conversion and conservation is a law that is universally applicable in nature. The following sub-blocks combine the current situation of the college entrance examination and propositional trends in recent years.
