it creates the air to beocme more polluted and creates oxygen as u burn it,
By burning it - usually (but not always) in order to turn water into steam, and using the steam to turn turbines.
Burning coal is a chemical process in which coal reacts with oxygen and forming carbon doxide and or monoxide.
When coal burns, it releases heat energy and produces carbon dioxide, water vapor, and other byproducts. The combustion process breaks down the carbon content in coal, releasing heat and energy that can be used for various purposes such as electricity generation or heating. However, burning coal also releases pollutants and greenhouse gases, which contribute to air pollution and climate change.
That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.
we release the potential energy to heat energy to do work
Coal burns when exposed to heat in the presence of oxygen to produce energy. If coal is not burning, it may be due to lack of sufficient heat, inadequate oxygen supply, or the presence of moisture which can hinder the combustion process.
When coal is burned without oxygen, it undergoes a process called pyrolysis where it decomposes into volatile gases, tar, and char. This can produce useful byproducts such as charcoal and coal gas, which can be used in various industrial processes.
Carbon in the form of charcoal or graphite reacts with oxygen in the air to produce carbon dioxide when it burns.
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.
Anthracite coal burns the hottest among the various forms of coal. It has a high carbon content and burns with a clean blue flame, making it a popular choice for heating purposes.
Yes, coal dust burns faster than a single lump of coal because it has more surface area exposed to oxygen, allowing for quicker combustion. This increased surface area allows for more efficient burning and a faster release of energy.
Anthracite coal burns the hottest among the types of coal as it has the highest carbon content and lowest moisture content.
