Now, with some heterogeneous mixtures, you can see the different phases with the naked eye.
有一些異種混合物，你用肉眼就能看到不同的狀態。
But that’s not so for all of them, like smoke, actually, that’s a good example because to the naked eye it looks uniform, like it’s a single phase.
但不是所有的都是這樣的，比如煙，實際上這是個很好的例子，因為在肉眼看來，它是一致的，就像只有單一的狀態一樣。
But if you magnify it, you can see that there are tiny solid and liquid particles suspended in the air.
但是如果你把它放大，會看到空氣中懸浮著微小的固體和液體顆粒。
So actually what you’ve got in smoke are three, three phases: solid, liquid, and gas, which you can separate by a process of filtration.
所以事實上煙里面有三種狀態：固體、液體和氣體，而通過過濾的步驟你可以把它們分離開來。
Another example, uh, dirty water, okay, dirty water is water that has suspended solid matter in it, that can be filtered too.
另一個例子是臟水，臟水是里面懸浮著固體物質的水，那也能被過濾。
Pass it through a filter and the dirt and whatever else is in there will stay behind in the filter paper.
讓它穿過一個過濾器，然后其中的灰塵和其他的物質會留在過濾紙上。
And the clean water will pass through it, again, depending on the size of the particles in the water, you might need magnification to see them.
而干凈的水會穿過它，還是一樣，根據水中顆粒的大小，你也許需要放大才能看見它們。
But even so, they can be detected, the boundaries are detectable, so multiple phases, okay?
但是即使如此，它們也能被發現，它們之間的界限是可檢測到的，所以它們有多種狀態。
