Question

Difference between densification and sublimation

Answer 1

$\huge\bold\pink{\underline{\underline{{ANSWER:}}}}$

$\bf{\underline\green{DENSIFICATION:}}$

⟹ An increase in the density of something. compaction, compression, concretion. concentration - increase in density.

$\bf{\underline\green{SUBLIMATION:}}$

⟹ Sublimation is a chemical process where a solid turns into a gas without going through a liquid stage.

Example :

✦ "Dry ice" or solid carbon dioxide sublimes.

Snow and ice can sublime in the winter months without melting.

✦ Moth balls sublime.

$\bf{\underline\green{DIFFERENCE:}}$

⟹ Sublimation and deposition are opposite processes.

⟹ Sublimation is when a substance goes from solid to gas while deposition is when a substance goes from gas to solid.

⟹ Sublimation and deposition chemistry are examples of phase changes.

⟹ This is evaporation, or the liquid phase of water going to the vapor phase of water.

Answer 2

sublimation is the process of converting a substance from solid to directly gaseous state without going into liquid state . deposition is the change of a substance from gaseous state to solid gas

example of sublimation is naphthalene balls

example of deposition is sub freezing air
