It sounds pretty silly, but it's really important because it allows you to define a thermometer and temperature.
这听起来相当白痴，但是它确实很重要,因为它让你可以定义,温度计和温度。
-
Yet, the temperature goes up. So, I can have a temperature change which is an adiabatic temperature change.
它与外界不会，有物质或者能量的流动,然而系统的温度升高了。
-
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。
-
That's another invention of the 1600s, by the way-- the thermometer. And they learned that concept-- perfectly natural to us--temperature.
顺便说一下,温度计也是十七世纪的发明,那时候的人才刚刚开始理解温度的概念,虽然对我们来说这是个很自然的概念
-
So if you had a jar full of triglycerides it would behave like an oil, many would be liquid at room temperature.
所以如果你有一满瓶甘油三酯,它看上去就好像油一样,它们在室温下都是液体
-
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。
-
OK, for most gases, T inversion is much 300K greater than 300 degrees Kelvin. Much greater than room temperature.
好，对大多数气体,转变温度都高于,比室温高很多。
-
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。
-
Now, we saw before, or really I should say we accepted before, that for an ideal gas, u was a function of temperature only.
我们已经看到,或者说我们已经接受这样一个事实，即理想气体的内能只和温度有关。
-
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
-
You've taken all the proteins inside the white of the egg, for example, you raise the temperature.
对蛋清部分所有的蛋白质,比如说进行加热
-
The last time you saw that for an ideal gas, the energy only cared about the temperature.
上次你们知道了，理想气体的能量只与温度有关。
-
In other words, now I know how to tell how the Helmholtz free energy changes as a function of temperature.
换句话说，我现在知道如何写出亥姆赫兹,自由能作为温度的函数。
-
It tells you what kind of molecule it is andgives you twovariables that are state variables You could have the volume and the temperature.
告诉你它是哪种分子,还给你了两个状态变量,它们可以是体积或温度。
-
The only function it is -- it doesn't care where the gas is. It only cares where the temperature is.
是温度的函数,它只是温度的函数,不管是什么气体。
-
H for an ideal gas is only a function of temperature. This is not true for a real gas fortunately, but it's true for an ideal gas.
不正确的,但是幸运的是,对于理想气体是完全正确的。
