Hot materials are not kept in a desiccator because the sudden cooling caused by placing a hot material in a desiccator can create a vacuum inside the desiccator, leading to potential implosion. Additionally, the hot material can release gases or vapors that may react with the desiccant or other substances present in the desiccator.

Why CaCl2 or silica is placed in desiccator Why should it be dried occasionally?
CaCl2 or silica gel is placed in a desiccator to absorb moisture from the air inside, keeping the contents of the desiccator dry. These desiccants need to be dried occasionally to regenerate their drying capacity by removing absorbed moisture, ensuring they can continue to maintain low humidity levels within the desiccator effectively.
What laboratory apparatus can keep 100 grams of a compount from absorbing atmospheri moisture?
The laboratory apparatus that can keep 100 grams of a compound from absorbing atmospheric moisture is a desiccator. A desiccator is a glass container or apparatus that is used mainly for drying and preventing moisture from the specimen.
What material shows something is hot?
Material can show that something is hot if it changes color, gives off light, emits steam or smoke, feels warm or hot to the touch, or increases in temperature when measured with a thermometer.
What piece of lab equipment to keep 100 grams of a compound from absorbing atmospheric moisture?
A desiccator is used to keep compounds dry by creating a dry environment with controlled humidity levels. Placing the compound in a desiccator with a desiccant, such as silica gel or calcium chloride, can help prevent it from absorbing moisture.
WHAT HAPPENS TO A DENTAL MATERIAL WHEN IT IS EXPOSED TO HOT AND COLD?
When a dental material is exposed to hot temperatures, it can soften or deform, affecting its physical properties. On the other hand, exposure to cold temperatures can make the material more brittle and prone to fracturing. These temperature changes can alter the performance and durability of the dental material.
Why can't hot objects be placed in a desiccator?
Placing hot objects in a desiccator can cause the temperature inside to increase beyond its safe operating range, potentially damaging the desiccant material and compromising its ability to absorb moisture effectively. Moreover, the abrupt cooling of the hot object can create a vacuum or pressure differential inside the desiccator, leading to potential implosions or explosions. It is recommended to allow hot objects to cool down to room temperature before placing them in a desiccator.
Why should the dried sample be kept in desiccator for cooling?
If a dried sample is warm, it will absorb water from the air while cooling. Placing it in a desiccator puts it in a dry atmosphere where no moisture is available to be absorbed from the air.
Why you should use desiccator to cool the hot salt?
A desiccator is used to remove moisture from the surrounding environment, not to cool down the salt. Cooling hot salt can be achieved by simply allowing it to cool at room temperature or using a cooling method such as placing it in a water bath.
What is a desiccator and how it is used?
Desiccator are sealable enclosure containing desiccants for preserving moisture
What is a desiccator most commonly used for?
A desiccator is commonly used to extract water from various articles of clothing. Also, if you manage to get your phone wet, you can use a desiccator to remove it.
Why would it be difficult to open the desiccator after its contents have cooled?
In the event that you have accidentally placed a hot sample inside a typical desicator (without stopcock), and partial vacuum build up. Plus heating don't help. One way to open the desicator is: PARTY RIBBONS or any thread like material that is fine enough and tough. Place the ribbon to the circumference of the desiccator and pull on both end so the string moves inward towards the center and break d partial vacuum.
How do you take care of desiccator?

Why must The Crucible by Arthur Miller be cooled in a desiccator?
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the experiment.
Who long you can left the simple in the desiccator?
I think you should resubmit this question as How long can you leave a sample in a desiccator? and it would help if you gave information about what sample you are putting in.
Why is a desiccator used to cool a crucible?
A desiccator is used to cool a crucible in order to prevent the absorption of moisture during the cooling process so an accurate result can be obtained
Why CaCl2 or silica is placed in desiccator Why should it be dried occasionally?
CaCl2 or silica gel is placed in a desiccator to absorb moisture from the air inside, keeping the contents of the desiccator dry. These desiccants need to be dried occasionally to regenerate their drying capacity by removing absorbed moisture, ensuring they can continue to maintain low humidity levels within the desiccator effectively.
What will happen when a cold material interacts with a hot material?
When a cold material interacts with a hot material, heat will transfer from the hot material to the cold material until they reach thermal equilibrium. This will result in the hot material cooling down and the cold material heating up. The rate of heat transfer will depend on the temperature difference between the two materials and their thermal properties.
