温度、内能与热量是初中热学中重要的、教学大纲中要求必须知道的物理量．这三个物理量都与物体内大量分子的热运动有关，是学习初中热学的基础．因此，要学好初中的热学，就必须正确理解并掌握它们之间的关系．一、温度温度是用来表示物体冷热程度的物理量，它是反映物体内部 Temperature, internal energy, and heat are important physical quantities in junior high school and must be known in the syllabus. These three physical quantities are all related to the thermal movement of a large number of molecules in an object and are the basis for learning junior high school thermals. Therefore, to learn how to learn junior high school, we must correctly understand and grasp the relationship between them. First, the temperature temperature is a physical quantity used to represent the degree of cold and heat of an object. It reflects the interior of an object.
