And specifically, when we talk about ionization energy, it's assumed that what we mean is actually the first ionization energy.
特别地，当我们讨论电离能的时候，我们默认,这指的是第一电离能。
-
And, in fact, if any electron comes in their midst, they'll capture it because the binding energy is so high.
事实上，如果电子从中间进来，它们会捕获它,因为束缚能是如此之大。
-
I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.
例如我们易于理解为什么，当试图测量一个不可逆系统的总能量，给出的或许。
-
As we go across the row what happens is that the ionization energy actually increases, and we can think about logically why it is that that's happening.
当我们沿着行,向右走的时候，可以发现电离能是逐渐升高的,我们可以从逻辑上思考一下为什么会这样。
-
The oil futures market is very significant because it represents the price of energy on dates into the future.
石油期货市场对我们来说意义重大,因为它代表,未来的能源价格
-
And what sublimation does is it just gives up the details and keeps the energy.
升华是指你放弃了具体对象,保存了能量。
-
I was just going to--I don't know if this is one of the things, you can eat it and you can metabolize it and trap the energy.
我想说,我也不知道说的对不对,可以食用,被代谢,并从中获取能量
-
And it turns out the second solution, with negative energy, was when the theory is telling you, hey, there are particles and there are anti-particles, and the negative energy when properly interpreted will describe anti-particles.
结果,后来证明,第二个根,也就是能量为负的那个根,正是理论的关键,世界上既有粒子,也有反粒子,负能量就是用来解释反粒子的
-
Now, if this incident energy is great enough it will take an electron out of the ground state and promote it.
现在，如果入射能足够的话,它会将一个电子从基态中释放出来,并且加速它。
-
So if we have a negative change in energy for any reaction as it's written, what that actually means is we're giving off energy as the reaction proceeds.
如果我们像这里写的这样,在任何一个反应过后，得，到的能量变化为负值,这就意味着我们在这个过程中放出了能量。
-
So we can't actually see any of that, it's too high energy for us to see. So everything we see is going to be where we have the final energy state being n equals 2.
所以我们是看不见它的,它能量太高了，我们能看见的,都是终态等于2的情况。
-
So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.
光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少，光的强度越大,光束能量越高。
-
So if you demonstrate something by writing an intelligent answer just by outlining it and saying, well, what I would do is I would equate the energy lambda and then solve for lambda, I can see that you know what is going on.
如果你想证明一些东西,通过写下一些很天才的答案,仅仅大致说一下，好的，我想做的是能量相等,然后解出，我能看到你知道怎么做。
-
And they've included too much or too little in the system, and it looks to them that the second law is broken and they've created more energy than is being brought in.
他们在系统中,包含了过多或过少的物质，从而在他们看来,第二定律貌似是被打破了,他们创造了比最初引入的更多的能量。
-
If you flip the Periodic Table over you will have the ionization energy of sodium, first ionization energy, 5eV and it is about 5 eV which, when you convert, 496kJ/mol is a whopping 496 kilojoules per mole.
如果浏览周期表,你可以得到钠的离子化能，第一电离能，大约，当你转换的时候，是巨大的。
-
That is, it gives us the relationship between energy and work and heat.
热力学第一定律阐述了,能量，功和热之间的关系。
-
This is the corollary. It's due to Clausius and it says the energy in the universe is conserved.
这是由克劳修斯得到的,这条结论说宇宙间总能量守恒。
-
OK, now, we're going to look at the internal energy, and we're going to pretend that it is explicitly a function of temperature and volume.
好，我们接下来看看内能，我们假设,它是温度和体积的函数。
