You're taking the air inside of the pump and you're compressing it. You're doing it so fast that there's not enough time for heat to come out of the gas that's inside the pump towards the walls of the pump.
你把空气吸进气筒里并且压缩它,你的动作很快以至于,没有足够的时间让热量,从气筒里面跑出来,传递到气筒壁上。
-
We add heat to the system.
我们对系统加热。

So Aaron, feeling the heat, makes a golden calf, and the people bow down to it, and someone declares, "This is your God, oh Israel, who brought you out of the land of Egypt."
所以亚伦，感受到躁动，造了一只金牛犊，人们朝它下拜，有人说，“这就是上帝，犹太人，这就是把你们带出埃及的上帝“
-
Passion seems to lie in coldness rather than heat, lies exactly in the restraining and disciplining of passion.
激情似乎存在于寒冷而不是酷热里，恰恰存在于,对激情的抑制。
-
If the temperature drops below a certain level it sends a signal, 'turn on the heat', and that signal stays on until it gets a negative signal to turn off.
如果温度降到一定程度以下时,探测器会发送一个信号,打开加热器,直到加热器再收到关闭的信号,它就会一直开着
-
So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.
重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。
-
What's happening there? Well, the selection of reactants has been done judiciously to provide either heat or to provide something that's cool.
就会感到这东西，比如说变冷了，对吧？,这里发生了什么？这些反应物都是,被仔细的选出来的，能够提供热量或制冷。
-
And the idea was that gravity did work on the water and falling, and that work led to the generation of heat.
焦耳的想法是,重力对水，做了功。
-
We're not going to have the constant pressure heat capacity, we're going to have the constant volume heat capacity, right.
这里出现的,不是等压热容,而是等体热容。
-
Now, the coefficient that relates the amount of heat in to the temperature change is obviously going to be different for these two cases.
在这两个例子中,很显然联系热量和温度变化的系数,是不一样的。
-
Virtue is to be fought for and raced for, not without dust and heat.
美德是要竞争和奋斗的，没有痕迹和温度。
-
And in practical terms, we can define the efficiency as the ratio of the heat in to the work out.
在实际中，我们定义,效率为热与功的比值。
-
I didn't even need to know that heat capacity of the product, right. Because it's effect the thermal mass of the product is negligible compared to the thermal mass of the calorimeter.
我甚至不需要知道生成物的,热容是多少，因为生成物的,热质量的作用相比于,量热计的热质量是可以忽略的。
-
We know it has to big anyway, since we can extract heat from it without changing the temperature.
我们知道它必须很大，因为我们得从中提取热量,但不改变它的温度。
-
So we don't really need to put in a certain amount of heat and change the temperature of the products and the calorimeter and so on.
所以我们实际上并不需要输入,一定的热量，改变生成物,和量热计的温度之类。
