Question

What is sublimation​

Answer 1

Answer:

Definition:-

The phenomenon of change of solid directly to gas or conversion of gas directly to liquid without changing into liquid state is called sublimation. For instance, camphor also called capoor when kept for a long time vanishes.

Example :-

The phenomenon of change of solid directly to gas or conversion of gas directly to liquid without changing into liquid state is called sublimation. For instance, camphor also called capoor when kept for a long time vanishes.Example :-Sublimation, including melting, freezing, and evaporation, is a form of phase transition, or shift in a state of matter. A substance transforms from a solid to a gas by sublimation without ever going through a liquid phase. A common example of sublimation is the dry ice, heavy CO2.

Application :-

Sublimation is used most extensively for separation of volatile components from non-volatile components. Hence, it is a useful preparative technique for recovery of compounds that can be sublimed at reasonable temperatures, at either atmospheric or reduced pressure.

Answer 2

$\fbox\pink{Answer}$

Sublimation is the transition of a substance directly from the solid to the gas state,[1] without passing through the liquid state.[2] Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.[3]
