Which equation represents sublimation?
1) [tex]Hg_{(l)}\to Hg_{(s)}[/tex]
2) [tex]NH_{3(g)}\to NH_{3(l)}[/tex]
3) [tex]H_2O_{(s)} \to H_2O_{(g)}[/tex]
4) [tex]CH_{4(l)} \to CH_{4(g)}[/tex]

Can someone help me with this one ?


Sagot :

Third one because sublimation is changing from solid to gas

Answer is 3) - HO(s) → HO(g)

Sublimation can be defined as the type of phase conversion of a substance which is in its solid phase to a gaseous phase without going through its liquid phase. 

According to the given choices only third one is correct because solid H
O goes to its vapor without going liquid state.
