比热力学能
补充资料：热力学能
热力学能是热力学系统内各种形式的能量总和，所以也称为内能。它包括组成系统的各种粒子（如分子，原子，电子，原子核等）的动能（如分子的平动能、振动能、转动能等）以及粒子间相互作用的势能（如分子的吸引能、排斥能，化学键能等）。热力学能用符号u表示，单位为j或kj。
热力学能的大小与系统的温度、体积、压力以及物质的量有关。温度反映系统中各粒子运动的激烈程度，温度越高，粒子运动越激烈，系统的能量就越高。体积（或压力）反映粒子间的相互距离，因而反映了粒子间的相互作用势能。物质与能量两者是不可分割的，所以系统中所含物质的量越多，系统的能量就越高。可见，热力学能是温度、体积（或压力）及物质的量的函数，因而是状态函数。
虽然热力学能是系统的状态性质，但其绝对值无法得知，只能利用热力学方法求出始终态热力学能的改变值，而这正是解决热力学实际问题的基本方法。
