Answer:
Explanation:
Burning coal is a chemical change called combustion. A combustion is the chemical reaction (redox reaction) of coal with oxygen O2. It is exothermic, which means it releases energy : hence the heat.
Burning coal is in fact not one type of combustion, but several types of combustion in competition producing CO2 and water, and other compounds such as small hydrocarbons and carbon monoxide.

No, I think that the mass after burning coal will not be changed. As any chemical reaction follows the law of conservation of mass, which states that mass can neither be created nor destroyed in a chemical reaction. The mass of the products will be same as the mass of products.
