A solid is matter that has a defined shape and volume. Because its particles are packed close together, a solid is rigid, doesn't flow, and isn't easily compressed. A solid is defined as a state of matter with a definite shape and volume. In contrast, liquids can change shapes, while gases can change both shape and volume.

Particle pollution — also called particulate matter (PM) — is made up of particles (tiny pieces) of solids or liquids that are in the air. These particles may include: Some particles are big enough (or appear dark enough) to see — for example, you can often see smoke in the air. Others are so small that you can't see them in the air.

On the other hand, as the micronization of solid particles, the specific surface area increases generally in reversal proportion to the particle size. In the above-mentioned case, when the particle of 1 cm is micronized to 1 µm and 10 nm, the specific surface area becomes ten thousand times and million times, respectively.

During wetting the solid/air interfaces of the particles are replaced by solid/liquid interfaces. Wetting can be enhanced by adding a wetting agent, or surfactant, to the liquid. This reduces the surface energy, or tension, of the liquid. ... The amount of weight lost (13.4%) can be used to calculate the weight proportion of the crystalline ...
