昇華作用（Sublimation）（化學高手請進）

This is a question related to AL Chemistry
Usually , we use a " Pressure - Temperature Diagram " to explain this phenomenon.
However , if you really want to understand why , you must have at least HKCEE Chemistry knowledge.
Otherwise , even I send you the diagram , you will never understand what the background theory is.

因為乾冰、臭丸中有其他物質，要分離佢地之中既物資，就要透過昇華去分離佢地!!!
碘同氯化銨都是會昇華的東西黎ga!!!

希望幫到你啦!!! =]

二氯苯,一般代替臭丸的1,4二氯對苯及很多是,等一等
