-
Sublimation is you might have a lot of energy, maybe sexual energy or aggressive energy, but instead of turning it to a sexual or aggressive target what you do is you focus it in some other way.

So if I worry about energy I have a pretty good chance of extracting out these heat capacities, right, and I don't have to worry about exactly which path and I can really mix things up.
而能量与热容有密切的关系,从能量就可以就算出这两个热容，我不需要考虑到底是哪一条路径,可以随意计算。

All right. So please raise your hand now if you think there'll be sufficient energy to eject electrons from the metal surface?
好的，如果你们认为,有足够的能量从金属表面,射出电子请举手？
-
Any frequency can't have an energy, you have to -- you don't have a continuum of frequencies that are of a certain energy, it's actually punctuated into these packets that are called photons.
任何频率不能有个能量,你必须要-对某一个能量上,你不会有连续的频率,光子实际上分立的存在。
-
Another way to say that it's going to be less, so you don't get confused with that the fact this is in the numerator here, there is that negative sign so it's less energy but it's a bigger negative number that gives us that less energy there.
另一个方式去说它将会变得很低实用，你们不用在这里的计算器的事实感到迷惑,这里有一个负号实用，它是更少的能量,但它是一个更大的数字,这里了它给了我们更少的能量。

这有3/5的能量，他们都是正的。
-
That is a lot of energy because there is a really solid bond.
这是很多的能量,因为这有一个真实固体键。
-
we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.
当我们从高到低时，我们说的,是发射,电子有多余的能量给出，这个能量等于，发出,光子的能量，当然我们可以通过方程,从能量知道，光子的频率，和波长。
-
Well, we can't guarantee with UV light we'll have enough energy to eject every single electron, so that's why when we use x-rays, they're higher energy, you can pretty much be guaranteed we're going to eject all of those electrons there.
好，我们不能保证紫外光有足够的能量,激发出每一个电子，所以我们要使用，X，射线，它的能量更高，你可以非常确定,我们可以激发出其中所有的电子。
-
And the word degenerate simply means same energy, are of equal energy when they're degenerate.

-
So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.
我们知道我们总是希望使我们的系统,处于能量尽可能低的状态，因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低，相较于分开时。

Gives you energy,' okay. Yes, so that would be the nutrient part of it.
提供能量",好的,作为食物需要有营养价值
-
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.
