Question

A kind of matter which can sublime is
a. water
b. plastic
c. milk
d. Iodine

Answer 1

Hint: Matter is defined as any material that has mass and occupies space by having volume in classical physics and general chemistry. Everyday objects that can be touched are ultimately made up of atoms, which are made up of interacting subatomic particles, and "matter" refers to atoms and anything made up of them, as well as any particles (or combination of particles) that act as if they have both rest mass and volume, in both everyday and scientific usage.

Complete answer:
Sublimation is the process of a material transitioning directly from a solid to a gas state without going through a liquid stage. Sublimation is an endothermic process that happens at temperatures and pressures below a material's triple point, which corresponds to the lowest pressure at which the substance may exist as a liquid in its phase diagram. Deposition or sublimation is the reversal of sublimation, in which a material transitions from a gas to a solid state. A solid-to-gas transition (sublimation) followed by a gas-to-solid transition has also been referred to as sublimation (deposition).
While vaporisation from a liquid to a gas occurs as evaporation from the surface if it occurs below the boiling point of the liquid and as boiling with the formation of bubbles in the interior of the liquid if it occurs at the boiling point, the solid-to-gas transition occurs as sublimation from the surface.
On mild heating, iodine generates vapours, however this is above the triple point and hence not genuine sublimation. By keeping the temperature just above the melting point of iodine, liquid iodine may be produced under atmospheric pressure. Iodine vapour can disclose latent fingerprints on paper in forensic science. At high temperatures, arsenic may also sublime.
Because they sublime significantly more than other common materials, cadmium and zinc are not appropriate for usage in vacuum.

Hence option d is correct.

Note:
The word "sublimation" is used to indicate a physical change of state rather than the chemical transformation of a solid to a gas. The breakdown of solid ammonium chloride into hydrogen chloride and ammonia upon heating, for example, is not sublimation but a chemical reaction. Similarly, the conversion of paraffin wax candles to carbon dioxide and water vapour is a chemical reaction with oxygen, not sublimation.
