exothermic
NO ... all burning/combustion reactions are exothermic.
When something burns it gives off heat. Therefore, it is exothermic.
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
Yes, burning coal is exothermic, in fact, that is why people burn coal. It produces heat.
Yes burning of coal is an exothermic reaction because energy is released in this process in the form of heat and light.

NO ... all burning/combustion reactions are exothermic.
Burning a match is an exothermic change because energy is being released.
When something burns it gives off heat. Therefore, it is exothermic.
Exothermic, for within an endothermic (situation) there would be a drop of temperature *excuse my spelling if you would* , therefore to continue burning it will need to absorb the heat, where as exothermic reactions energy will be released as heat.

Yes, burning coal is exothermic, in fact, that is why people burn coal. It produces heat.
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Yes burning of coal is an exothermic reaction because energy is released in this process in the form of heat and light.
