What is the physical state of pure caffeine crystal?
if you are looking at this you must be at the absolute stage of being bored.
What purpose did the vacuum serve during the sublimation purification of caffeine?
it is used because some organic compounds do not sublime at atmospheric pressure so by using the vacuum it substantially reduces the pressure so that they can be purified by sublimation. it also makes decomposition and melting less likely to occur during the sublimation.
What temperature does iodine begin to sublime?
Vaporization of iodine occur after 113 oC.
Can ammonium chloride sublime from room temp?
Yes, ammonium chloride can sublime at room temperature. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through the liquid phase. Ammonium chloride has a relatively low sublimation temperature, allowing it to sublime easily at room temperature.
How fast does mothball sublime?
depends on temperature. Very slowly at room temperature.

Why does graphite sublime?
Graphite does not sublime or melt under normal room temperature. However; it does sublime if the temperature reaches 3652-3697℃.
Why does Caffeine sublime?
Caffeine sublimates because it has a relatively low vapor pressure at room temperature, allowing it to transition directly from a solid to a gas without passing through a liquid phase. This phenomenon occurs due to the molecular structure of caffeine, which allows its molecules to escape into the vapor phase under certain conditions. Sublimation is more pronounced in substances with weaker intermolecular forces, and caffeine's structure facilitates this process. Consequently, when exposed to heat or reduced pressure, caffeine can readily sublime.

Ammonium chloride has a relatively low sublimation temperature, allowing it to sublime easily at room temperature.
What do you mean by sublime at room temperature?
Sublime at room temperature means a substance changes directly from a solid to a gas without passing through a liquid phase. This process is called sublimation.
How fast does mothball sublime?
depends on temperature. Very slowly at room temperature.
Does Mercury sublime?
Yes, Mercury can sublime, or transition directly from a solid to a gas at certain conditions. Because of its low boiling point, Mercury can evaporate at room temperature, creating a vapor that is toxic to humans.
At what temperature does diamond sublime?
Neither graphite nor diamond melt when heated - at a temperature of about 4800 °C, they sublime into gases. It takes a lot of energy to make them sublime as many strong covalent bonds need to be broken.
