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.
The burning of natural gas is an exothermic process.
Burning leaves is an exothermic process because it releases heat and light energy as a result of the chemical reactions that take place during combustion.
No, burning sugar is exothermic because it releases energy in the form of heat and light. The chemical reaction between sugar and oxygen produces carbon dioxide and water, along with energy that is released in the form of heat and light.
It releases heat, therefore it is an exothermic reaction.
Exothermic
It is an endothermic process.
Burning a match is an exothermic change because energy is being released.
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.

Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
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.
The burning of natural gas is an exothermic process.
Any time you burn something, it's exothermic.
Burning leaves is an exothermic process because it releases heat and light energy as a result of the chemical reactions that take place during combustion.
