PROFESSOR: No. So, compared to the atoms, it should be somewhat the same energy, we shouldn't get any extra stabilization from forming the molecule.
不会，所以和原子相比，它的能量相同，形成分子并不会带来额外的稳定性。
-
So, having other particles around that have the same energy that you could technically add up if you were adding them up like a wave, you can't do the same thing with particles, they're all separate.
所以，如果它们是波,你可以把其他的,拥有相同能量的粒子加起来，但是你不能把这些粒子加起来，因为它们是分离的。

Being in a warmer environment,up to a point, will lead to decreased energy expenditure and therefore, at the same amount of food intake,weight gain."

If it's symmetric, that means that each bond has exactly the same energy.
这意味着如果他们对称，那么每根键的能量是一样的。

Smith says growth in the solar energy industry could be a boon for the environment and the economy at the same time.

In the case here, tha t I just illustrated with the little cart going down the valley, would be exactly the same with regular energy, the equilibrium state is one of lowest energy, right.
在现在所考虑的情况下,我刚才所描述的小车沿着山谷下行，结论会像能量判据一样，平衡态是能量最低的态。

-
All four of these orbitals have the same energy, t hey're degenerate.
这四个轨道,能量相同,是简并的。
-
That's what we call degenerate orbitals, they're the same energy.
我们称之为简并轨道，它们具有相同的能量。
-
And I want to really highlight here we're talking about for a hydrogen atom orbitals - with the same n value have the same energy.
我想强调的是,我们所说的,都是对单个的氢原子,和言的,对于同样的n值能量相同。
-
So, for example, if we're talking about the n equals 2 state, all of these four orbital descriptions are going to have the same energy.
例如，当我们说n等于2的态，所有这四个轨道的能量,都是相同的。
-
And the other thing to point out is that the energy that an anti-bonding orbital is raised by, is the same amount as a bonding orbital is lowered by.
另外一个要指出的事情是,反键轨道引起的能量升高，和成键轨道引起的能量降低是相同的。
-
That is to say I can now reroute that sodium plus chlorine reaction and go a different way, but I still end up with the same change in energy.
也就是说，我可以重新定义一种,钠与氯的反应途径,从另一种途径来实现反应，但是能量的变化过程相同。
-
So any time I draw these molecular orbitals, I do my best, and I'm not always perfect, yet trying to make this energy different exactly the same for the anti-bonding orbital being raised, versus the bonding orbital being lowered.
所以我在画这些分子轨道的时候，虽然不是很完美，但我总是尽量,让反键轨道引起的，能量升高和成键轨道。
-
You just change volume to pressure and basically you're looking at enthalpy under a constant -- anything that's done at a constant volume path with energy, there's the same thing happening under constant pressure path for enthalpy.
可以看到这就是把体积换成了压强,一般我们都是在一种恒定状态下,考虑焓的，任何在恒容条件下,能伴随能量变化的东西，也在恒压条件下伴随焓同样地变化,所以你可以经常。
-
We can do the same thing for the other observed kinetic energy.
我们还可以对观测到的,其它动能进行同样的操作。
-
Is the energy going to be the same as up here?
这里的能量,也是一样的吗？
-
And again, our energy is going to be the same where we again only depend on the n value.
同样的能量，和以前一样,因为它,只决定于n的值。
-
The sum of path number 2 and path number 3 get me to the same place, so the energy change by going through this time path, this intermediate point here back all the way to final state should be the same the red path.
而经过路径2和3可以3,到达同样的末态，因此经过路径,2和3带来的能量的变化，与路径1带来的,能量变化相同。
-
It's going to be the same energy.
是一样的。
-
px And I arbitrarily chose to put it in the 2 p x, 2pz we also could have put it in the 2 p y or the 2 p z, it doesn't matter where you double up, they're all the same energy.
我任意地选择放入至，我们也可以把它放入2py或，它与你在哪双倍填充没有关系，它们都在相同的能级。
-
They're not interacting at all so that's why the energy is the same as that for two individual atoms, that's what we're dealing with. As we get closer together, we start get lower and lower in energy.
它们之间没有任何相互作用，因此,体系的能量就等于两个分开的原子的能量，这就是我们要处理的，而随着我们的距离越来越近，我们的能量开始变得越来越低。
-
- The same place is that energy is a function of these four quantum numbers.
它就是这个结论,能量是这四个量子数的机能显示。
-
So what we're doing is filling in those eight electrons following the Aufbau principle, so our first electron is 1s going to go in the 1 s, and then we have no other options for other orbitals that are at that same energy, 1s so we put the second electron in the 1 s as well.
它会是什么样子呢,我们正在做的是将这8个电子按照奥弗,堡原理进行填充,所以我们第一个电子将会进入，然后我们没有其他的,轨道的选择在同一个能级，所以我们把第二个电子也放入。
-
When we talk about the n equals 2 state, we now have 2 squared or 4 degenerate same energy orbitals, and those are the 2 s orbital.
当考虑n等于2的态时，我们有2的平方,或者4个简并能量的轨道，它们是2s轨道。
-
All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.
这节课就到这里,下节课将由Bob，Field讲授,我们将学习功与热量的关系，认识到它们在本质上的相同之处，并通过热力学第一定律，亦即能量守恒定律，把它们联系起来。
-
So those should be raised and lowered by the same energy.
引起的能量降低相等。
-
And we can generalize to figure out, based on any principle quantum number n, how many orbitals we have of the same energy, n and what we can say is that for any shell n, there are n squared degenerate orbitals.
我们可以总结出来，在，主量子数为n的情况下，同一个能量上，有多少个轨道，我们可以说，对任何壳层，有n平方个简并轨道。
-
And again, you'll notice that our energy is absolutely the same for an electron in that 2px and 2s orbital.
同样，你们会发现2px轨道的能量,和2s轨道是一样的。
