Question

"Odonil" bar reduce in size after a few days because

Answer 1

$\LARGE{\underline{\sf{\purple{Required\: Answer:}}}}$

Odonil is a volatile solid and can directly change into gaseous state which reduces its size. The process behind the above phenomenon is:

• Sublimation

━━━━━━━━━━━━━━━━━━━━

Coming to the definition, Sublimation is the process followed by volatile solids to change into gaseous state without undergoing the liquid state. Volatile solids are the ones which evaporates easily. The Odonil bar contains the same solid and reduces its size due to the fragrance released by it.

The fragrance got mixed with the air, reducing the size of the bar. Eventually, one day the solid will vanish without living any trace, just fragrant air around it....

Answer 2

Required Answer:

Odonil bar reduce in size after a few days because It can change into gaseous form which reduce its size..This done by an process called sublimation...

Extra Info:

What is Sublimation?

Sublimation is the transition of a substance directly from the solid to the gas state,[1] without passing through the liquid state

Uses of Sublimation:

Used in purifying processes,used in making naphthalene balls,used in room freshners and in drying processes without leaving any residue

Example of Sublimation:

solid carbon dioxide sublimations, which can be used to create a smoky or spooky special effect. Due to its relative safety, dry ice is the solid of choice in classroom demonstrations.
