Soot particles are the result of incomplete combustion of carbon or organic compounds.
If you think to black soot this is formed from tiny carbon particles.
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
Diesel fuel produces the highest levels of soot when burned because it contains more carbon molecules compared to other fuels like gasoline. The incomplete combustion of diesel fuel leads to the formation of fine carbon particles, known as soot, as a byproduct.
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.

Diesel particulate pollution refers to the microscopic particles emitted from diesel engines, which can pose health risks when inhaled. These particles are a component of air pollution and can contribute to respiratory issues, cardiovascular problems, and other health concerns. Various regulations and technologies are in place to reduce diesel particulate pollution and its negative impacts on public health and the environment.

Modern Diesel cars often have a diesel particle filter (DPF) installed in the exhaust to trap fine soot particles and stop them getting into the athmosphere.

Heat and pressure in the injection system can cause soot-like carbon particles to form in the fuel. These particles are small (on the order of 10 microns or less).
Dust is very fine particles of soil or ash and soot is very fine particles of carbon.
Getting covered with soot would be classified as a physical change rather than a chemical change.
Soot particles are lighter than air and rise due to convection currents created by the heat of the fire. As the soot rises, it cools and mixes with air, forming smoke. The smoke is a combination of the soot particles and other gases and particles produced by the combustion process.
Soot is primarily composed of carbon particles that result from the incomplete combustion of organic matter such as wood, coal, or diesel fuel. It may also contain trace amounts of other substances such as ash, sulfur compounds, and organic compounds.
Emigreen® Soot reduction systems use a monolithic ceramic filter that is extremely efficient at capturing the soot particles emitted by diesel engines. To optimise filtration efficiency and extend the operational life of the filter, the particulate matter that builds up in the filter has to be removed. The process of burning off the accumulated soot is known as filter regeneration. See Emigreen for more info: emigreen.eu/solutions/soot-reduction/
