**Short Note on Gas Carbon**

Gas carbon, also known as carbon black, is a form of carbon that is produced through the process of destructive distillation of coal or by heating petroleum products at high temperatures.

1. **Formation**: Gas carbon is generated when coal undergoes destructive distillation, which involves heating coal in the absence of air. This process breaks down the coal into various components, one of which is gas carbon. Similarly, when petroleum products are subjected to high temperatures, gas carbon is formed as a byproduct.

2. **Physical Properties**: Gas carbon is characterized by its compact nature and amorphous structure. It appears as a gray solid and is often found deposited on the walls of the containers that hold it. This deposition occurs due to the condensation of carbon particles when the gas cools down.
