“氢键”这个名字使用不当，因为它不是真正的键，而是特别强的极性分子间的吸引力。

The name "hydrogen bond" is something of a misnomer, as it is not a true bond but a particularly strong dipole-dipole attraction.

增加热量不能时分子变大，而是使分子间的平均距离增大。

Adding heat does not make the molecules any larger; it makes the average distance between them larger.

油能与水分开，是因为油分子之间的作用比油水分子间的作用强。

Oils segregate out of water because the oil-oil interaction is more favorable than the oil-water interaction.

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。
