Question

Any three substances that undergo sublimation

Answer 1

Understanding the concept:

• Sublimation is defined as a process in which a solid directly changes into a gaseous form without wetting the surface.
• The absorption of heat provides enough energy for certain molecules to overcome the attraction forces of their neighbors and escape into the vapor phase, causing sublimation.

Examples of substances that undergo sublimation:

• Dry Ice, Mothballs (Naphthalene), and iodine are three examples of substances that undergo sublimation
