thermal energy是【热能】,即内能的别称,是一个系统所拥有的状态量,我们可以说一个系统有多少thermal energy；而heat是【热量】,是一个只有在热传递过程中才有意义的过程量,我们只能说在某个过程中系统“吸收”或“放出”了多少heat,而不能说系统“有”多少heat,heat是不能“有”的.
温度是average kinetic energy大小的宏观体现.对一个确定的物体而言,温度也就是thermal energy的宏观体现.想想thermal这个单词的意思吧!组成物质的微粒间有相互作用,所以微粒有potential energy.物体中所有微粒的动能和势能之和就是internal energy.Heat特指热传递过程中转移的那部分能量.虽然这些书都没有对这三个概念...
Lake Tyrifjord consists of Holsfjord and Steinsfjord, two lakes of highly contrasting morphology, was used as the basis for a comparison of internal energy, the work of the wind, and thermal stability in two lakes under identical large-scale climatic conditions. Because of simultaneous temperature...

O2 [4] batteries) have attracted more and more attention for stationary energy storage because of their high theoretical specific capacity (1165 mAh g–1 for Na and 687 mAh g–1 for K), low redox potential (–2.71 V vs. standard hydrogen electrode (SHE) for Na+/Na and –2.93 V vs....
