Ans➡️Heated samples and beakers, or weighing dish, are cooled in a desiccator to prevent the sample or beaker from gathering moisture as it cools. The interior of the desiccator is dry due to the desiccant at the bottom and because it is sealed to keep outside, moist air from getting inside.

Hope this helps you ☺️⭐✨✨⭐✌️✌️

Answer:

Desiccator is a sealable container which maintains a low humid atmosphere for the preservation of moisture sensitive substances. Desiccators are mostly dehydrating agents or strong oxidizing agents.

Explanation:

Desiccators are used to protect chemicals which react with humidity present in the air. It is also used for cooling of heated objects as well as for the storage of dry objects that are hygroscopic and water sensitive. It contains a suitable drying agent known as desiccant which helps with this process.

It is prepared by heating tetraphenylcyclopentadienone and diphenylacetylene in benzophenone or other high-temperature solvent.

Heated samples and beakers are cooled in a desiccator which stops the gathering of moisture as it starts to cool down. The inside of the desiccator is dry because of  the desiccant at the bottom and as it is sealed it prevents the humidity from getting inside.
