在热学中,内能、温度、热量是本质不同的三个基本物理量,同学们往往弄不清它们之间的关系,在学习过程中应注意把它们区别开来.内能:指物体内部所包含的总能量,它既包括分子无规则热运动的动能,分子之间的相互作用的势能,还包括分子原子内的能量,原子核内的能量等.在热学中,由于 In thermals, internal energy, temperature, and calories are three fundamental physical quantities that are different in nature. Classmates often cannot understand the relationship between them. In the learning process, they should be noted to distinguish them. Internal energy: refers to the internal space of objects. The total energy contained, which includes both the kinetic energy of the molecular’s irregular thermal motion, the potential energy of the interaction between the molecules, and also the energy within the molecular atom, the energy within the nucleus, etc. In thermals, due to
