Is burning gasoline an exothermic process or an endothermic process?
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.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is wax in a candle burning an exothermic process or endothermic?
Burning a candle is an exothermic process because it releases heat energy. The chemical reaction between the wax and oxygen produces both light and heat, making it exothermic.
Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
Is sparkler burning endothermic or exothermic?
Endothermic reactions take in heat from the surroundings (and make it cooler), exothermic reactions give out heat to the surroundings making it hotter. Get too close to a sparkler and you'll find it is very hot! This is because it is an exothermic reaction.
Is burning alcohol an exothermic or endothermic process?
Exothermic
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
Is paper burning with a bright flame is endothermic or 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.
Is paper burning with bright flames exothermic or endothermic?
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.
Is burning petrol exothermic or endothermic?
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
Is paper burning with a bright flame a exothermic reaction or endothermic reaction?
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.

Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
Is burning 2-propanol endothermic?
Any time you burn something, it's exothermic.
Is burning leaves a endothermic or 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.
Is burning sugar endothermic?
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.
