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]
Answer (3)
Third one because sublimation is changing from solid to gas
Answer is 3) - H ₂ O(s) → H ₂ O(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** ₂ O goes to its vapor without going liquid state.
The equation that represents sublimation is 3) H 2 O ( s ) → H 2 O ( g ) , which indicates solid water transitioning directly to vapor. Sublimation is defined as the phase change from solid to gas without passing through the liquid state. The other options represent different phase changes that do not define sublimation.
