What happens when S is heated in the absence of air?
When S (sulfur) is heated in the absence of air, it undergoes sublimation, meaning it changes directly from a solid to a gas without passing through a liquid state. This process results in the formation of a colorless gas with a characteristic odor of sulfur dioxide.
When coal is heated in the absence of air what is the gas called?
The gas produced when coal is heated in the absence of air is called coal gas. It is a mixture of various gases such as methane, hydrogen, carbon monoxide, and carbon dioxide.
What happen when sulphur is heated in the absence of air?

Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
Why must coal be heated in the absence of air to change into coke?
Coal needs to be heated in the absence of air to turn into coke because oxygen in the air would react with the coal and burn it, preventing the transformation into coke. Heating the coal in the absence of air allows the volatile components to be driven off, leaving behind a more solid and pure carbon structure, which is coke.

What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
