The molar volume is being changed a little bit trying to make things collide with each other, they can't occupy the same volume.
摩尔体积发生了很小的改变,如果你试图使气体分子间相互碰撞,他们不能占据同一个位置。
If we have too much gas in here, in other words, if the gas is at too high a pressure, the collisions with the gas molecules will consume the energy of the electrons and, again, we will see nothing.
假设这里有过多气体,换句话说,如果气体处在一个高压状态下,气体分子间的碰撞将会消耗,电子的能量,同样,什么也没有。
That's how tight the junctions are, not even a small molecule like glucose can pass between them.
可见胞间连接多么紧密,甚至像葡萄糖这样小的分子也不能通过
Because the molecules are farther apart from each other. So the energy goes up.
因为分子间的距离,扩大了。
Because of that, if I eat something that's rich in glucose, so it has lots of sugar molecules, the sugar molecules can't pass between the cells.
因此,如果我吃了富含葡萄糖的食物,尽管其含有很多的糖分子,但糖分子不能从细胞间通过
If z is greater than 1, then the real gas means that the atoms and molecules in the real gas are repelling each other and wants to have a bigger volume.
如果Z大于,说明实际气体的分子间斥力较强,体积比理想气体要大,我们可以查表找到。
So the real pressure is not quite the same because of this attractive force as it was, as it would be without the attractive forces.
气体压强,由于分子间的吸引作用,会比理想气体要小,这样,我们应该修正p的值。
