If you chop wood for a fire and then burn the wood you have made both physical and chemical changes.?
Yes, chopping is a physical change: the chemical composition of the molecules inside the wood remains the same. Burning causes the molecules in the wood to react with the air (mostly with the oxygen in the air), and the result is different compounds than before.
Is burning of wood an example of an oxidation reduction reaction?
Burning Wood is similiar to Volcanic Ash
Is a spark a type of reaction?
An electrical spark is not. It is merely electrons flowing and that may cause a reaction. A fire type spark, is not either, but the fire is. A 'spark' that is a slmall ember of burning substance that 'jumps' from a fire is a burning material, so there is a chemical reaction of burning, also called oxidation, going on.
How is charcoal obtained from wood?
Partial burning of wood produces charcoal
Why will a container of gas explode if it is heated?
heat causes pressure, pressure causes friction, friction causes spark, spark causes KABOOM! all in a split second
How a change in thermal energy causes matter?
A burning wood fire, when cooled down or extinguished, leaves wood ashes.
Why is wood burning chemical energy?
how chemical energy produce in firewood useful
What kind of heat energy is burning wood?
Burning wood is the process of converting chemical energy in the fuel into thermal energy. Heat transfer is the process of moving thermal energy from one object to another. There are different types oh heat transfer including radiation, conduction and convection. Basically, the wood burning is a spontaneous process, theoretically, but in order for the process to become under way something called the activation energy must be overcome, which means that an energy of that magnitude must be applied to the wood to get it burning (oxidising). This usually comes in the form of a spark or a flame from your lighter. So once you apply that activation energy from your lighter, the wood begins to burn, and the burning of the wood itself produces heat to propagate the process. So long as there is oxygen, fuel (such as wood or octane for example) and the initial spark, then you have fire!
What are the three main causes of air pollution?
the three main causes for air pollution are burning wood,coal so much use of vehicles,etc.
Is wood burning an example of combustion?
Yes, wood burning is an example of combustion.
Burning wood a physical or chemical?
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
What causes a 1982 Honda Silverwing 650 to keep burning out spark plugs?
Wrong heat range plug for the fuel and/ or riding conditions
What wood sparks a lot while burning?
Wood that is damp tends to spark alot. I have burned wood to heat my house for years, and am very familiar with wood types, and I have not found that answer to be correct. Certain types of wood just spark a lot, I don't know why. Hedge is the hottest burning wood I know of and is also the worst offender in the spark category. It seems that any yellow colored wood is a bad sparker, such as hedge (aka osage orange) and black locust and mulberry. They spark a lot, burn hot, and are yellow colored wood. The best overall wood is white oak, as it splits fairly easy, and burns really hot, but not too hot like hedge (it will melt your grates) has almost no sparks and lasts a long time.

Industrial burning wood manufacture plant?

Why does burning wood and burning fossil fuels produce similar pollutants?
Burning fossil fuels and burning wood produce similar pollutants because wood and fossil fuels are both consist of hydrogen and carbon. Carbon dioxide is produced when burning wood and fossil fuel.
Free wood burning patterns?
Free wood burning patterns have instructions on how to use the pattern. Woodworkers Woodshop and Carving Patterns have free patterns for wood burning. Another option is that you can draw a pattern by hand for your wood burning project.
