4 Questions
What is sublimation?
Sublimation is the process in which some solids change directly to vapors without passing through the liquid state.
Give three examples of substances that undergo sublimation.
Iodine, benzonic acid, and ammonium chloride are examples of substances that undergo sublimation.
Describe the process of sublimation shown in Figure 5.14.
In Figure 5.14, violet-black crystals of iodine are heated. The dark crystals of iodine deposit on the underside of a glass watch placed on top of a beaker containing solid iodine. The iodine vapor sublimates from the crystals in the beaker and condenses to form crystals on the glass watch.
What is the purpose of heating the solid iodine in the beaker?
The solid iodine in the beaker is heated to cause sublimation, where the iodine vaporizes directly from the solid state to form crystals on the glass watch.
Test your knowledge on sublimation and learn about the fascinating process in which certain solids transform directly into vapors without becoming liquids. Explore the examples of substances that undergo sublimation, such as iodine, benzonic acid, and ammonium chloride. Discover the phenomenon through an intriguing illustration of the sublimation of violet-black crystals of iodine.
