Question

Non Volatile substances can undergo sublimation.
A. True
B. False

Answer 1

Hint:Sublimation process can be stated as transition of a substance from the solid state to the gaseous state not by passing via the liquid state.

Complete step by step answer:
A non-volatile substance can be stated as a substance which does not readily evaporate into a form of a gas under current going conditions. Non-volatile substances show a low vapour pressure and along with a high boiling point.
Sublimation process can be stated as transition of a substance from the solid state to the gaseous state not by passing via the liquid state. Non-volatile compounds are unable to vaporise and thereby, cannot undergo sublimation.

Hence, Option B is correct.

Additional Information:
A non-volatile substance known as a substance that does not easily evaporate into a form of gas under current going conditions. Non-volatile substances show a low vapour pressure and along with a high boiling point. Sugar and salt are the 2 examples of non-volatile solutes. And the examples of volatile substances involve alcohol, mercury, and gasoline.
Sublimation is a phase transition type, or a variation in a state of matter, just similar to melting, freezing, and evaporation. By sublimation, a substance gets changed from a solid to a gas state not by passing via a liquid phase. Dry ice, solid CO2, are common examples of this process.
Iodine and ammonium chloride forms fumes on applying gentle heat while sodium chloride does not undergo sublime.
The solid substance that goes through a change to produce gas is called sublime.

Note:
A non-volatile substance known as a substance that does not easily evaporate into a form of gas under current going conditions while, Sublimation process can be stated as transition of a substance from the solid state to the gaseous state not by passing via the liquid state.
