The temperature scale that turns out to be well—defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

理想气体温标它有精确的定义，并能引出绝对零度的概念。

If that's not zero, unlike the ideal case, now unlike before, where we just had entropy driving the mixture, now there's an energy of mixing.

如果那不是零，和理想的情况不同，和以前不同，以前我们只有熵来驱动混合，现在有混合能。

This is zero. So again, in the ideal liquid mixture case, their molecules aren't interacting.

这是零，又一次，在理想液体混合物的情况下，它们的分子没有相互作用。

And the temperature scale that turns out to be well-defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

比如理想气体温标,它有精确的定义,并能引出绝对零度的概念,今天我们就先来谈谈它。

B=0 There's going to be some temperature where B is equal to zero. In that case, your gas is going to look awfully like an ideal gas.

在某个温度,这时，实际气体的表现，十分接近理想气体,高于这一温度它是正的。

This quantity is exactly zero for an ideal gas and we'll discover why eventually it has to do with what we mean by an ideal gas it turns out.

对理想气体它是零,这点我们接下来会知道是,为什么，这与为什么我们叫它理想气体有关。

Competition between banks will tend to bring the lending and borrowing rates closer together, theoretically squeezing bank profits to zero in the ideal case of a perfectly competitive market.

Apparently they figured sub-zero nighttime temperatures and treacherous road conditions are ideal for showing off the stability management technology in their 911, Panamera and Cayenne variants.
