I know that Arsenic sublimes directly when heated. So I want to know which other elements like this sublimates on heating throughout the periodic table. I also know dry ice.
thanks
thanks
Dry ice is not an element. Otherwise, all substances can sublimate: it is just a question of pressure.Prins said:I know that Arsenic sublimes directly when heated. So I want to know which other elements like this sublimates on heating throughout the periodic table. I also know dry ice.
Sublimation is the process in which a solid directly turns into a gas without passing through the liquid phase. The elements that can directly sublime include iodine, carbon dioxide, and dry ice.
Yes, any element can be sublimed under specific conditions such as low pressure and high temperature. For example, sulfur can be sublimed at temperatures above 119 °C and a pressure of 1 atm.
Yes, sublimation has various practical applications in industries such as food preservation, printing, and air conditioning. It is also used in laboratories for purifying substances and creating vacuum conditions.
Sublimation differs from other phase changes because it involves the direct conversion from solid to gas without passing through the liquid phase. This is different from processes like evaporation and condensation, which involve a change in temperature or pressure.
The rate of sublimation is affected by factors such as temperature, pressure, surface area, and air flow. Higher temperatures and lower pressures can increase the rate of sublimation, while larger surface areas and increased air flow can also speed up the process.
