《内能及其利用》是初中物理九年级上册《机械能和内能》章节的内容,也是中考的考点内容之一,如何才能更好的了解内能以及其利用情况,本文对内能及其利用方面的知识进行了归纳和总结,希望能对大家有所帮助.一、内能的概念:1.内能:物体内部所有分子做无规则运动的动能和分子势能的总和,叫做物体的内能.2.物体在任何情况下都有内能:既然物体内部 “Internal energy and its use” is the junior high school physics ninth grade “mechanical energy and internal energy” chapter content, is also one of the senior high school entrance examination content, how to better understand the internal energy and its utilization, the internal energy and its Using the knowledge of induction and summary, hoping to be helpful to everyone. First, the concept of internal energy: 1. Internal energy: all molecules within the object to do random movement of the kinetic energy and molecular potential energy, called the object’s internal Yes .2. An object has internal energy under any circumstances: Since the object is inside
