PS3B - 能量和能源转移


Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between objects with different temperatures. He explains how heat is transferred via conduction, convection and radiation.

下一代科学标准物理科学纪律核心思想3B - 能源与能源转移

Paul Andersen解释了如何在系统内保存的能量。在宏观和微观碰撞中,碰撞前的能量量等于后的能量。然后,他将热量定义为具有不同温度的物体之间的能量转移。他解释了如何通过传导,对流和辐射转移热量。
