Why didn't they keep right on going with G, H, I, J, K, L, M, N, O, P?
为什么他们不接着写下去呢,按照字母表
So for an ideal gas then, dH/dp under 0 constant temperature, that has to be equal to zero.
所以对于理想气体,偏H偏p在恒温下,等于。
H-P and private investigators found no violation of the sexual harassment policy at the company.

PH3 We have p h 3.
我们有。
Mr.Hurd became chief executive officer five years ago after H-P ousted Carly Fiorina.

Pressure has dropped out of the picture completely here. So there is no p dependence here.
理想气体的H只是温度的函数,这对于真实气体来说是。
But they did find that Mr.Hurd violated H-P's Standards of Business Conduct.

Therefore, from experiments, u is only a function of temperature for an ideal gas, H and therefore from these experiments, 0 we come out with delta H dH/dp is equal to zero.
因此,从实验可以得出,对于理想气体u只是温度的态函数,因此从这些实验中我们得到Δ,偏H偏p等于。

So if you're working with cyanide in the lab as potassium cyanide or sodium cyanide, those are what are called p h s's, it's a rating for different kinds of chemicals.
因此如果你在实验室中,需要用到氰化物,比如氰化钾或者氰化钠,这就是所谓的,“P,H,S“,这是化学药品有害程度的一个级别。

What is dH/dT as a function, keeping pressure constant, what is dH/dp, keeping temperature constant?
恒定时偏H偏T是什么,温度恒定时的偏H偏p又是什么呢?,好的,让我们解决第一个问题?
Under his leadership H-P stock doubled in price.

H We also saw that dS for constant H and p was greater than zero.
我们同样可以看到如果保持自由焓,和压强不变熵的变化dS也是大于零的。
Adiabatic q equal to zero. It's also delta H 0 which is zero. The two didn't necessarily follow because remember, delta H is dq so p is only true for a reversible constant pressure process.
在这个过程中ΔH等于,绝热的所以q等于0,而ΔH也等于,这两个也不一定有因果关系,因为,记住,ΔH等于dq只有在恒压。
H=qp The u plus p V. Delta H is equal to q V.
括号里面的就是H,等于u+pv,Δ
Now, before, of course, in the first part of the class u we started out looking at u H and then looking at H not as functions of S and V or S and p, but as functions of temperature, mostly.
现在,在本课的前一部分,我们首先讨论了,然后讨论了,这两个量并未写成S和V或者S和p的函数,而是写成了温度的函数。
I change the temperature, what does that mean?
只改变温度,偏H偏p是多少?
OK, in a few weeks, you're going to find out that we can calculate dH/dp from this equation of state, and you're going to find p out that dH/dp from that equation of state b-a/RT is proportional to b minus a over RT.
好,在接下来几个星期里,你们将知道从这个状态方程,可以计算出偏H偏p,并且你们会发现,从这个状态方程得到的偏H偏,正比于。
T Remember, we're trying to get delta H, p we're trying to get dH/dT constant pressure and dH/dp constant temperature. OK, these are the two things were trying to get here.
想要得到在恒压状态下的偏H偏,和在恒温状态下的偏H偏,好的,这是两个我们,在这里想要得到的东西。
So if you had a high temperature, this a small compared to b. If you're negative which means that dT/dp at constant H is less than zero.
高于反转温度,这一项相比于b很小,意味着H恒定时,偏T偏p小于零。
