Question

Write on prnciple ,technique and examples on sublimation

Answer 1

hala mate,

Principle of sublimation:

Sublimation has a solid turning into gas directly, during the process, there is no passing into liquid phase. The solids have a weak intermolecular force. As to the compound’s triple point, the ability of any types of solids to sublimate based on its phase diagram typically the lower the pressure,the lower the sublimation temperature.

Technique of sublimation:

Sublimation is a technique used by chemists to purify compounds.

Examples of sublimation:

Dry Ice - Solid carbon dioxide is known as "dry ice" and sublimates at room temperature.

Freeze-drying - Water can be sublimated in a food product by using a vacuum.

hope it helps!!!
