What is sublimation? Explain the methods?
Answers
The process in which a solid substance when heated changes directly into its gaseous state without changing into its liquid state, is called sublimation.
Explanation :-
In general scenario, when a substance is heated, it melts to liquid at a specific melting point.
Further, when this molten liquid heated, it coverts into a gas at temperature called as boiling point.
The step of liquid formation is absent in sublimation.
So the process of conversion of states of matter is solid converts to liquid and this liquid boils out to give gas.
Solid →liquid→Gas (normal transition of matter).
Solid→ Gas (Sublimation phenomenon)
So the process is devoid of liquid state during transition.
