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...

We discuss the relation of the excess specific heat, the excess energy per area, and the thermodynamic Casimir force in thin films. A priori these quantities depend on the reduced temperature t and the thickness L0 of the film. However finite-size scaling theory predicts that the scaling funct...

The sources of internal heat gains (IHG) include: PEOPLE (sensible and latent heat gain) LIGHTS (sensible heat gain only) EQUIPMENT (a) Receptacles or electrical plug loads (sensible heat gain only) (b) Processes such as cooking (sensible and latent heat
internal energy noun , Thermodynamics. a function of thermodynamic variables, as temperature, that represents the internal state of a system that is due to the energies of the molecular constituents of the system. The change in internal energy during a process is equal to the net heat entering ...

Although the simultaneous production of heat and power, the so-called combined heat and power (CHP), is from a thermodynamic point of view still the most efficient energy conversion method, cogeneration units have nowadays problems to position themselves in the current and future energy market. The...
