• 它把压强、体积、温度联系在一起。

    It relates the pressure, volume, and temperature together.

    youdao

  • 我们之前不是讲过,越到海洋的深处,压强就越大吗?

    Didn't we talk before about how the deeper down into the ocean you go, the greater the pressure?

    youdao

  • 我们在化学中所做的很多都是在恒定的温度和压强下进行的。

    So much of what we do in chemistry does take place with constant temperature and pressure.

    youdao

  • 我们关心的大多数过程都是在保持压强、温度或体积不变的情况下发生的。

    Most processes that we're concerned with will happen with something held constant like pressure or temperature or volume.

    youdao

  • youdao

  • 这个参考压强,我们一般选作一巴。

    And this reference pressure, we took as one bar.

    youdao

  • 当然,我们可以继续降低压强。

    Of course, we can continue to lower the pressure.

    youdao

  • 现在,可以把压强再升高一点。

    Now, I could raise the pressure a bit higher.

    youdao

  • 如果改变压强,那么就会有问题。

    If you change the pressure, then you're in trouble.

    youdao

  • 温度和压强,可能是一个大气压。

    Pressures and temperature, maybe one bar, let's say.

    youdao

  • 我们知道压强等于力除以面积。

    We know the pressure is equal to force per area.

    youdao

  • 那么将要发生的是,压强变高。

    So what's going to happen, then, is the pressure is higher.

    youdao

  • 因为里外不处于同样的压强下。

    Because these aren't at the same pressure.

    youdao

  • 但是这个分压是总压强的函数。

    But it's a function of the total pressure.

    youdao

  • 我们会降低压强,体积就会变大。

    We're going to drop the pressure, the volume is going to go up.

    youdao

  • 来看第二个,总压强对反应的影响。

    I'm going to go to the second one, which is the effect of the total pressure on the reaction.

    youdao

  • 在同样的压强和温度条件下。

    The same conditions of pressure and temperature.

    youdao

  • 膨胀,压强降低,所有的都回到气态。

    Expand it, lower the pressure, all goes back into the gas phase.

    youdao

  • 没有气体,我们要降低压强。

    No gas. And now we're going to bring down the pressure.

    youdao

  • 所以如果把压强从一巴升高到100巴。

    So, you increase the pressure from one bar to 100 bar.

    youdao

  • 所以这就是我们的总压强。

    So there's our total pressure here.

    youdao

  • 我能告诉你总压强是多少。

    And I'm telling you what the total pressure is.

    youdao

  • 在这里,增加压强,压强上升。

    And I increase the pressure, pressure goes up.

    youdao

  • 比如压强和温度,或体积和压强。

    For instance, the pressure and the temperature, or the volume and the pressure.

    youdao

  • 我想知道p,总压强,作为yB的函数。

    I want p, total pressure, as a function of yB.

    youdao

  • 这里系统没有对环境做功,因为压强是零。

    And there is no work done on the surroundings because pressure is zero.

    youdao

  • 你最终会有更大的压强。

    You end up with a larger pressure.

    youdao

  • 当液面升高的时候,这里的压强就增加了。

    If the liquid level goes up, it raises the pressure down here.

    youdao

  • 这意味着里面的压强,比外面的压强高?

    And what that means is the pressure inside here must be higher, right?

    youdao

  • 总压强看起来是一样的。

    Total pressure is going to look the same.

    youdao
