Coal dust burns fast because it has a high surface area-to-volume ratio, allowing more oxygen to react with the dust particles simultaneously. This increased oxygen availability accelerates the combustion process, causing coal dust to burn quickly.

Can coal go on fire?

Yes, coal can catch fire and burn because it is a combustible material. When exposed to high enough temperatures, coal can undergo combustion and release heat energy. However, coal fires can be dangerous and difficult to extinguish, making them a significant environmental hazard.


Is coal dust a mineral?

Coal dust is not considered a mineral. Here’s why: Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystalline structure. Coal, on the other hand, is an organic material formed from the remains of ancient plants. It does not have a consistent chemical formula or crystalline structure, so it doesn't meet the strict definition of a mineral. Coal dust is just fine particles of coal — so it's still organic, and still not a mineral. However, coal dust can contain trace amounts of minerals, especially if mixed with other rock or impurities from the mining process. But as a whole, it’s not classified as a mineral. 4o


What burn quickly powered coal small pieces of coal or lumps of coal?

when coal is pulvorised(powder ) the surface area will be more so it cathes fire early than lumps.


A spark can cause coal dust in a mine to explode and yet not cause an explosion with charcoal in a barbecue grill?

Yes. * A) Coal is not charcoal * B) Charcoal is not dust * C) The coal mine has a different atmosphere to the grill So, with all those differences, why would we expect the two situations to produce the same results?


When you burn coal does the mass stay the same?

Your question isn't rigorous enough. When you burn coal you are combining carbon from the coal with oxygen in the air. So the mass of Carbon Dioxide created is greater than the original mass of coal. There is no mass destroyed however, you just have to be more rigorous in the parameters of your question.

What if we put coal on ice and burn the coal?

it will burn it would probably burn at first and melt the ice and water does not encourage burning so the coal stops burning


How many homes can a single coal-fired plant support?

It can support at least 1 because it will be able to burn out really fast so for at least 30 and a half mins


Why a spark can cause coal dust in a mine to explode and yet not cause an explosion with charcoal in a barbecue grill?

It is a question of the fuel oxygen ratio. Coal dust has a very high mix rate and as such will burn so quickly it is a form of explosion. A briquet has a very low surface area and is not as volatile. Note that any dust will explode. Flour has always been dangerous and grain silos are built to contain massive explosions.

What happens when people burn fossil feels?

Fossils are mostly minerals, so unless they are very high in carbon, such as coal, they will not burn.

How could you see a meteor but not hear?

It is just a small piece of ice, dust or rock burning up in the sky as it enters Earth's atmosphere. They are high in the sky and so make little or no noise as they burn, so we do not hear anything. They burn extremely fast, lasting a fraction of a second sometimes, so it all happens very quickly.

Why mix oil and air is explosive?

Oil can burn. If finely dispersed in air, it can burn real fast. So fast that it'll look like an explosion.


Why can't astronomers use a telescope to study the entire surface of the moon?

The moon has no atmosphere, so there is nothing there to burn up the dust and dirt and ice and rocks, turning them into meteors, as happens on Earth. Meteors seen on Earth are so brief and fast and enclosed by the atmosphere, and so far from the Moon that you would not see Earth's meteors from the Moon.The moon has no atmosphere, so there is nothing there to burn up the dust and dirt and ice and rocks, turning them into meteors, as happens on Earth.
