对于“内能和内能的利用”部分,同学们需要掌握以下知识点:通过自然界和生活中的一些简单热现象,了解分子热运动的一些特点;知道分子动理论的基本观点;了解内能和热量;从能量转化的角度认识燃料的热值;了解比热容;了解热机的工作原理;知道内能的利用在人类社会发展史上的重要意义。下面我们来看看中考是如何考查这些知识点的,在中考复习过程中,又将着重注意哪些问题。考点一分子动理论对于分子动理论这一考点,中考命题时以简单基础题为主,中考应考时特别需要注意分子的无规则运动是自发的,不能与物 For the section on “Use of Internal Energy and Internal Energy,” students need to know the following points: Understand some characteristics of the molecular thermal movement through some simple thermal phenomena in nature and life; Understand the basic ideas of molecular dynamics theory; Understand Internal energy and heat; from the energy conversion point of view of the calorific value of fuel; understand the specific heat capacity; understand the working principle of heat engine; know the use of internal energy in the history of human social development of great significance. Here we take a look at how to test the knowledge of these knowledge points in the exam review process, they will focus on what issues. Examination of a molecular theory of Momentum theory for the test of this test, a simple basic questions in the senior high school entrance examination test-based, especially when exams need to pay attention to molecular irregular movements are spontaneous, not with the material
