qB This must be heat q B, right. So again, but now let's also look at our special function.
这个不是,这应该是热量,对吧?所以又一次,这些是我们熟悉的。
Delta u, delta H, familiar state functions, q w changes in their values, q, w, heat and work.
U,△H,很熟悉的态函数,它们的值在变化;
"Jeez Louise," said John Q.Public.

Let me give you, I'm going to create, q a polar point, I'm going to call it q, and we'll give it some random values.
让我给大家讲解下,我要去创建,一个极坐标点,然后我会去命名它为,然后我给它赋一些随机的值,好,现在我想知道。
That's the most outstandinganswer I've ever heard. You must havea goddamn I. Q Of 160.
VOA: standard.other
I am going to highlight this by calling this q1, lower case q being the charge here on the nucleus.
我要把它称作q1来进行强调,小写q是指原子核上的电量。
The state require sa minimum I. Q of 80 to attend public school.
VOA: standard.other
And let me use a big Q to be the total quantity produced-- sorry--the total quantity demanded in the market.
用Q代表总产量,对不起,是市场总需求量
His I. Q is 75. Well, we're all different, Mr. Hancock.

For isothermal expansion, that means that delta u does not change, but delta q is equal to delta w?
在等温过程中,是不是内能不变,Δq等于Δw?
U OK, so let's look at delta u. Delta u is q plus w.
好的,让我们看看Δ
q1 The heat input is just q1, Q and we'll define that as capital Q.
输入的热是,我们把它定义为大写的。
w And that has to equal q plus w, summed up for all the steps.
等于q加,对所有过程相加。
u=q+w We have a relationship between them.
它们之间有关系Δ
u=q+w All right, what is delta u? delta u is q plus w.
好,Δu是多少?Δ
w Now, we have u, q and w.
现在我们有u,q和。
So just to emphasize that the strategies are quantities, rather than using S let me use Q today to be the strategies.
为了突出策略就是商品的产量,这次我们用Q来表示策略而不用S了
What's q for this process here? Anybody?
这个过程的q是什么?有人知道吗?
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
And lower case q sub 2 is the charge on the electron.
小写q加个下标2是指电子所带电量。
q Delta u is w2 prime.
等于零,q,is,zero。,Δu等于w2一撇。
Sorry, the question was, what happens if I said p is less than q?
抱歉,问题是,如果我这里写p小于q的话?
Q So it's just capital W over capital Q, q1 which is to say it's minus all that stuff over q1.
所以效率就是W除以,等于负的所有这些之和除以。
So q is zero adiabatic. Work is zero.
因为系统绝热,所以q是零。
All right, q has to be just the opposite of this because we've already figured out that there's no change in u.
好,q一定与它,相差一个符号,因为我们已经,指出U是不变的。
q Work is zero. Delta u is w plus q, work plus heat. This is zero, this isn't.
功是零,△U是w加,功加上热量,这个是零。
du We can talk about du for the system well, w that's q plus w.
我们可以讨论它的,等于q加。
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。
Cp And delta T is given by the heat, which has to do with how much of the candle burnt, divided by the constant pressure heat capacity.
T等于热量q除以恒定的等压热容,其中热量与,蜡烛燃烧的多少相关。
