Question

Which of the following does not sublime?
A. Ammonium chloride
B. Dry ice
C. Sodium chloride
D. Iodine

Answer 1

Sublimation will be defined as a sort of state change, or a change within the state of matter, rather like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without even passing through a liquid phase.

Complete answer:
Sublimation may be a chemical change where a solid turns into a gas without probing a liquid stage.
An example of sublimation is when ice cubes shrink within the freezer.
The definition of sublimation is that the process when socially unacceptable impulses become more socially acceptable acts and feelings. Sublimation is a very unique process and it does not occur in all substances.
The meaning of sublimation is causing something to vary from solid to a gas, without becoming a liquid.
The process of adjusting from a solid to a gas without passing through an intermediate liquid phase. dioxide, at a pressure of 1 atmosphere, sublimates at about −78 degrees Celsius. Ice and snow on the Earth's surface also sublimate at temperatures below the melting point of water.
The transformation of an impulse into something socially constructive.
Now let's come to the answer.
Sodium Chloride is an ionic solid and has high melting and boiling points. So it can't change in vapour phase simply at gas pressure hence it cannot sublime.
Ammonium chloride, solid and iodine undergo sublimation which on heating without coming within the liquid state directly converts during a gaseous state.

So the correct answer is C.

Note:
Sublimation happens when a solid changes directly into gaseous state without undergoing liquid state. Evaporation is the process when a liquid changes into gaseous state when exposed to suitable heat at its boiling point. Vapourization is the phenomenon of phase transition from liquid to gas. Evaporation is an example of vapourization, but sublimation is not.
