Question

What is the process by which a solid changes directly into a gas?

Answer 1

We have to know that sublimation is the difference in state where a strong changes straightforwardly into a gas. A. Losing or Gaining Energy When most substances lose or acquire energy, one of two things happens to the substance, its temperature changes or its state changes.

Complete answer:
We have to know that sublimation is the progress of a substance from the strong stage to the vaporous stage without changing into the fluid stage. This interaction is an endothermic stage change that happens at a temperature and pressing factor beneath the triple mark of the substance. De-sublimation or testimony is the converse of this cycle wherein a gas is straightforwardly, changed over into a strong state.
Components and mixtures primarily have three distinct states at different temperatures.
The change from strong state to vaporous state requires a progress of strong state to fluid state and fluid state to a vaporous state.
In the event that solids have adequate fume pressure at a specific temperature then they can be straightforwardly eminent into the air.
Solids, which have a high pressing factor at their triple point, show sublimation.
The triple point is where the pressing factor and temperature of the substance are with the end goal that it can exist in each of the three conditions of issue at the same time. The triple point is a trademark point of a substance.
There are different instances of sublimation, which are capable of us in our regular day to day existence.

Note:
We have to know that the best illustration of sublimation is dry ice, which is a frozen type of carbon dioxide. At the point when dry ice gets presented to air, dry ice straightforwardly changes its stage from strong state to vaporous state which is apparent as mist. Frozen carbon dioxide in its vaporous state is more steady than in its strong state.
