在热现象的研究中,内能、热量和温度是三个重要的物理量。它们三个是既相互间独立,又彼此有关联的物理量,所以很容易混淆。温度是表示物体的冷热程度,从分子运动论的角度看,它是表示某一时刻该分子热运动的剧烈程度。由于物体的分子在永不停息地做无规则运动,所以 In the study of thermal phenomena, internal energy, heat, and temperature are three important physical quantities. The three of them are physical quantities that are both independent and related to each other, so it is easy to confuse. Temperature is the degree of coldness and heat of an object. From the perspective of molecular kinematics, it is the intensity of the thermal movement of the molecule at a certain moment. Because the molecules of the object never stop doing random movements, so
