The stuff that's inside the reacting volume, and whatever's right around it there inside the big box, it's all going to heat up.
都会升温，对吧？,在反应容器里的东西,以及大箱子里的任何东西，他们都会变热。

Heat up the library all the time.
要天天泡在图书馆里。

Her face became purplish except for little, white marks over it that didn't heat up.
她的脸几乎变成了紫色，还有些白色的小斑点。

You want to keep spinning your mandrel so that it doesn't melt off the rod and you're going to heat your bead so that it's tacky enough to roll onto the frit and pick up pieces of the glass."

Remember this one's running backward, we're pumping heat up.
请记住这个热机是反过来运行的，我们把热量向上传输。

(CANNED HEAT - "GOING UP COUNTRY") And this was how the New York Times described Woodstock: "Bethel townspeople gazed in awe at the streams of hippies, but they murmured 'PEACE' to the visitors, offered free water and returned smiles.

As I'm sure you know, we're able, with various lower organisms, to put them in a state of suspended animation and then, the amazing thing is, if you heat them back up again properly, they start functioning again.
我想你们一定知道，我们能够使各种低等生物，进入假死状态,而后令人称奇的是，如果将它们正确地重新升温，它们又会重新恢复功能。
-
The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.
原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开
-
If it does, then the whole thing will heat up, right?
如果是这样，整个这些东西？
-
We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.
为了得到液氦,不能再常温,做这个实验,否则就是加热氦气，因为室温高于它的转变温度,所以焦耳-汤姆孙，实验会加热氦气。
-
Compression you're expected to heat up, right?
压缩会升温，没错吧？
-
You know from experience if you've ever mixed them to make salad dressing, they don't mix too well. And you may know that if you heat them up, they mix much better.
经验告诉我们,你无法把它们混合做成色拉酱调料，他们不会很好的混合，但是你也知道,如果我们把他们加热，就能够混合的更好。
-
There's an interplay between the energy inside the gas which is the heat energy which is allowing me to do all that work to be outside, and so I'm using up some of the energy that's inside the gas to do the work on the outside.
即使没有热传递,能量也能以,做功的形式传递出去，气体的一部分内能,转化成了功。
-
And these verbal descriptions lead to some pictures that I put up and I'll put up again about how you might try to accomplish something like run an engine or move heat from a colder to a warmer body.
这些言语的描述有助于你们理解我讲过的,而且还要再讲的一些物理图像,比如一台发动机,是怎么运行的,或热怎样从冷的物体传到热的物体。
-
This is providing work that's being used in here, but if you take the whole outside of the surroundings and this whole thing is the system, no net work, these things cancel each other, and yet heat's going up.
如果把外面的全部当成环境，把这里的全部当成系统,那么就没有净的功，它们相互抵消了，热量向上传输，会发生什么？
-
And it's for that whole unit that you've got some heat capacity. How much heat does it take the warm the entire thing up or the insides of the thing up by a degree? It's that number right.
由这个单位你能知道,一些热容的信息，要让这整个装置,或里面放置的东西,升温一度需要多少热量？
-
Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.
也能改变温度，绝热指的是没有热传递，在非绝热条件下，也同样可以升温,比如用火或者热源加热，这样，q也应当与路径有关。
-
I can take a heat pack, like the kind you buy at a pharmacy. Break it up. It gets hot.
买来的热装罐在里面打破,它就变热了。
-
You take your fuel, you heat it up again.
然后移开热源。
-
It expands. You change your constraints on your system, you heat it up some more, then you take the heat source away, and you put it back in contact with the atmosphere. And you cool it a little bit, change the constraints, cool it a little bit more, and heat, and you've got a closed cycle engine.
让它与大气接触冷却,改变约束，使它继续冷却，然后又再次加热,这就是循环热机，我们以前也研究过，更复杂的机器。
