It is dangerous for solids or liquids to enter the trachea because the trachea is designed to carry air to the lungs, not food or fluids. Inhalation of foreign objects can lead to choking, obstructing airflow, and causing respiratory distress. Additionally, aspiration of liquids can result in aspiration pneumonia, as harmful substances may enter the lungs and cause infection or inflammation. Prompt medical intervention is often necessary to prevent serious complications.

Solid
Sublimation is the process when a solid changes directly into a gas without first becoming a liquid. This occurs when the conditions are such that the solid phase can bypass the liquid phase and enter the gas phase.
The ancient method of getting liquid mercury in to solid is like this. They will put the solid thing by subjecting it in a high temperature. As temperature arises mercury would rise too. And they will collect it. But it is too dangerous. They might be poisoned.
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
it is a gas
Sublimation is the phase change that changes a solid directly to a gas or vapor without first changing to a liquid. In this process, the solid particles gain enough energy to break free from the solid structure and enter the gas phase without passing through the liquid phase.
A gas is not a liquid or a solid.
