Answer 2

Substances that sublime on heating are camphor and Ammonium chloride

Explanation:

• Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation.
• Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid $CO_2$, provides a common example of sublimation.
• Phase transitions are dependent upon the temperature and pressure of the material in question.
• Under normal conditions, as generally described by kinetic theory, adding heat causes the atoms within a solid to gain energy and become less tightly bound to each other.
