When wood is burned in a closed container its mass does not change law theory or observation?
That is a law, specifically the law of conservation of mass. This states that matter can neither be created nor destroyed in a chemical change. This was proved in Lavosier's experiment where he determined that the total lass of the products formed by burning were equal to the mass of the matter burned and oxygen consumed.
What is the meaning of red hot cinder?
A cinder is a small piece of burned wood or coal that is still sparking even though it has been mostly burned. A small leftover piece of firewood that is still solid and burning without flame is an example of a cinder. Some cinders have cooled on the surface and are, deceptivley, no longer red in color.
When a piece of wood burns it releases?
When a piece of wood burns, it releases heat energy, water vapor, carbon dioxide, and ash.
What type of fuel is wood?
Wood is considered a biomass fuel. It is a renewable energy source that can be burned to produce heat and energy. Wood fuel is commonly used in residential heating systems such as stoves and fireplaces.
Do the products in a chemical reaction have the same prperties as the reactants?
In a chemical change chemical properties often change (like a substance's melting point or it's reactivity). In a physical change the materials have the same properties (a physical change would be like crushing rocks into sand). You can take wood, grind it into saw dust, but it is still wood. But if you burn it, the wood goes through a chemical change with the oxygen in the air and most of it is broken down into a gas (smoke) and the solid of which is left behind has a very different flammability property. (Suit, it doesn't burn.)
What is a piece of burned wood or partly burned wood as in a fireplace?
charcoal
What happens to the shape and volume of the block of wood and piece of stone when burned?
When burned, the block of wood will decrease in shape and volume due to the release of gases like carbon dioxide and water vapor. The piece of stone, on the other hand, will not be affected by burning and will retain its original shape and volume.
What are the energy transformations of a burning piece of wood?
When a piece of wood is burned, the potential energy stored in the wood is converted into thermal energy (heat) and light energy (flame). This process is an example of chemical energy (stored in the wood) being transformed into thermal and light energy.

Why is wood special?
Wood is a very useful product. It can be used to build structures, burned for fuel, or turned into other products like paper, art, and tools.
Partially burned piece of coal or wood called?
A partially burned piece of coal or wood is typically referred to as "charcoal." Charcoal is formed when organic material, such as wood, is heated in a low-oxygen environment, causing the volatile compounds to evaporate, leaving behind a carbon-rich residue. Charcoal is commonly used as a fuel source for cooking and heating due to its high carbon content and ability to burn at high temperatures.
Are any new products being formed when chopping wood?
No, chopping wood involves breaking down the existing wood into smaller pieces without creating any new products. The end result is just smaller sections of the original wood log.
If you burned some bread you would be left with a black powder.The same thing would happen if you burned a piece of wood .what is the black powder and what happens to the other elements?
that black powder is called carbon
Why is shapening a pencil a physical change?
no new chemical products are formed .there is only a change in shape .the products after and before are same that is wood and graphite
When wood burns what is made?
Wood combustion results to two products, carbon dioxide and water. As the solid wood disappear, some ashes remain. These are formed by minor components of wood that cannot burn.
What is the density of a piece of wood?
It depends of the piece of wood itself and the type of wood that it is.
How many calories does wood have when burned for fuel?
When burned for fuel, wood releases about 3,800 to 4,800 calories per pound.
