What kind of minerals are flammable?
Sulfur is a flammable mineral; also coal, petrol, organic salts etc.
What flammable liquid is obtained by the distillation of coal tar or petroleum?
Benzene is a flammable liquid that is obtained by the distillation of coal tar or petroleum. It is commonly used as a solvent in various industrial processes and as a starting material in the production of other chemicals.
Why do coal mines explode?
Coal dust in the air is an explosive mixture, because the mixture of coal and air can burn much more rapidly than solid pieces of coal can (flour in the air is also explosive, or sawdust - any flammable substance in the form of dust becomes explosive if it is mixed into the air). The process of mining coal is messy, and creates a lot of dust. And any spark can set it off. No smoking in the coal mines!
Is tar flammable?
no since it is a mineral its the softest mineral so it's not flammableAnswer:Tar is a hydrocarbon. All hydrocarbons (even coal which is essentially pure carbon) are flammable. Industrial burners use hot tar (usually referred to as Bunker C) as a fuel. It is cheap. The flash point for tars (temperature at which they may be ignited ) ranges from 100oC to 300oC
How does coal gas lighting work?
Coal gas lighting involves burning coal gas, which is produced by heating coal in the absence of air to release flammable gases. The gas is then piped to a burner where it is mixed with air and ignited, producing a bright flame for lighting purposes. The gas flow can be controlled to regulate the brightness of the light.
Are bricks flammable?
Bricks are not flammable, but coal bricks are. IF THERE IS A BETTER ANSWER, IMPROVE.
What are non-renewable flammable materials made from plants and animals?
Coal
Is coal dangerous?
yes because its flammable it could burn your hand up
What is a serious hazard of coal mining?
Fire and explosion. Coal mines contain methane gas, which is very flammable. There are also health hazards from breathing coal dust.

What were the sorts of incidents that happened in coal mines?
The greatest dangers were fire/explosion, and collapse of the areas being mined. Coal dust is highly flammable, and most coal deposits have methnae gas (VERY flammable). Collapse could result in being trapped in the mine, or hit by rocks. Accidents have also happened when working with explosives, operating power machinery, and electrical wiring.
What is benjene?
Benzene is a colorless volatile liquid hydrocarbon. It is present in coal tar and petroleum during chemical synthesis. It is flammable and has a sweet smell.

What flammable gas is found underground?
One example of a flammable gas found underground is methane. It is produced by the decomposition of organic matter in the absence of oxygen and can be found in coal mines, landfills, and oil and natural gas reservoirs.
Why a spark can cause coal dust in a mine to explode and yet not cause an explosion with charcoal in abarbeque grill?
Open flames were used to help miners see until the advent of portable lighting. There was a massive amount of dust flying around coal mines, and it is very flammable. When it's a fine powder, it becomes explosive. The reason charcoal does not do this with a grill is because charcoal is made from wood products, not coal, and is not nearly as flammable or capable of producing the fine particulate dust that can combust easily.
