Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Sublimation | The property of solid directly changing into gaseous state is called sublimation |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| List of sublimation elements | List out different compounds which are sublime and at what temperatures they get vaporized |
Real life uses :
Separation of salt from Ammonium chloride
Practical examples around us
| Examples | Explainations |
|---|---|
| When ammonium chloride and salt is heated, then ammonium chloride is formed at the walls of the inverted funnel | Ammonium chloride is sublime, as we heat it ammonium chloride changes into gaseous form and at the edges of the funnel it forms a powder of ammonium chloride |
