In other words, if we don't have to worry about entropy or volume equilibrium is achieved when energy is at a minimum.
换句话说,如果我们不担心熵,和体积的平衡,那么能量就得是最小的。
And the bigger lesson from that is that entropy, unlike energy u or enthalpy H, we could define an absolutely number for it.
热力学第三定律的一个更重要的推论是,与内能和自由焓不同,我们可以给上定义一个绝对的数值。
Still, the actual equilibrium depends on entropy also, not only on the energy.
而且,实际的平衡依赖于熵,而不仅仅是能量。
There's a balance here between ordinary energy or enthalpy and entropy.
通常所说的能量,或者自由焓和熵之间存在一个平衡。
That is, you've got lower energy on the right and also higher entropy.
这表明,你降低了能量,同时增加了熵。
So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.
关键在于,这种能量与熵之间的平衡,确定了平衡的条件,在化学中能量涉及键能,而熵和无序有关,即有多少可能的不同组合或者形位,二者的平衡会告诉我们平衡态是什么样子。
