热量和内能是物理学中两个重要的物理量.内能是能量的一种形式,是物体里所有分子无规则运动的动能和分子势能的总和.而热量是物体之间或同一物体的不同部分发生热传递时传递能量的多少,实际上就是在物体之间或同一物体不同部分发生的被转移的那部分内能. Heat and internal energy are two important physical quantities in physics. Internal energy is a form of energy, which is the sum of the kinetic energy and molecular potential energy of all the molecules in an object that moves irregularly, and the heat is the difference between objects or different parts of the same object The amount of energy transferred when heat transfer occurs is actually the energy transferred within or between different parts of the same object.
