Heat capacity relates the amount of heat that you add to the system to the change in temperature, and this is the relationship.
热容联系起给系统提供的,热量和温度的变化，关系式是这样的：
-
That's the property that's going to give us the change in temperature.
这就是能给我们,温标定义的物质特性。
-
We control how we use time, we control the temperature in the environment, and hermetically seal ourselves in things.
我们控制时间的利用，我们控制周边环境的温度,我们把自己封闭在各种事务中，与世隔绝。

That is to say brick work in high temperature furnaces, maybe tiles on the Shuttle, to resist high temperatures because of the high internal bonding.
它在能够承受高温炉的温度，例如瓷砖，能够耐受高温,因为它们有强的内部键作用。

- And now temperature in Fahrenheit -- 212 all right, let's go ahead and pick an easy one like 212, Enter, and indeed equals 100 in Celsius.
现在输入华氏温度-,好的，让我们选一个简单的，像，回车，确实等于100摄氏度。
-
Another experiment would be to mix two chemicals together and put a thermometer in and measure the temperature.
比方说做这样一个试验,将两种化学试剂混合然后测定反应温度
-
Because that's the temperature at which many of the molecules in our bodies operate at their most efficient, and enzymes is the best example of that.
因为在正常体温下,体内许多分子活性最高,酶就是其中最好的例子
-
There is a change in temperature, right?
温度会改变，对吧？
-
so I'm heating up the system in this path here, and then to connect the 2 endpoints here, a constant temperature path.
需要再用，一个等温过程，这两个状态。
-
If you double everything in the system, the temperature is not going to change, it's not going to double.
如果你把系统中所有的东西增加一倍，温度是不会变的，它不会跟着增加一倍。
-
In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.
这个值，效率，当低温热源的温度1,是据对零度时可以达到一。
-
If you have a large number of atoms in an aggregate, it is going to require that the substance turn solid and condense at room temperature.
如果有很多原子进行聚集，在室温下,会使的物质转变成固体状态。
-
Avogadro was a professor of chemistry at the University of Turin who did a lot of work on gas laws, understanding the number of gas particles in a given volume at a given temperature.
阿伏加德罗是一个化学教授,在都灵大学,他做了很多关于气体定律的研究，了解气体微粒,在特定的容量和温度下的数目。
-
But we've defined the enthalpy of those elements in their stable state at room temperature and pressure as zero, right?
但我们已经定义了这些,元素处于它们室温和常压下,最稳定的状态时的焓为零，对吧？
-
What we define as zero is the enthalpy of every element in its natural state at room temperature and ambient pressure.
我们将零点定义为每种元素,在室温和正常大气压下,在其自然状态下的焓。
-
To ask questions like how much heat is released in a chemical reaction that takes place at constant temperature.
当我们想要知道,当一个化学反应在恒定的温度下发生时,会放出多少热量时。
