Converting wood to sawdust involves physically breaking down the structure of the wood into smaller particles. This change is irreversible because the original composition of the wood is permanently altered when it is reduced to sawdust, making it difficult to revert back to its original form without significant effort or energy input.
It depends on how you bend the wood. For example, if you steam it, it is reversible. But if you cut notches, it is not reversible.
Reversible.
No. You must not confuse the PROCESS of converting some chemical products to others, with the RESULT. The PROCESS of converting wood and oxygen to smoke is a chemical change. The SMOKE itself is not.
Physical-it is still wood, just in small pieces

The reversible change is coffee dissolving in water. Boiling water, melting chocolate, and burning wood are irreversible changes.
if you chop down a tree and cut it into a bunch of little peices... can you put that tree back together so that it can continue on living its boring tree life? the answer is no it is irreversible
Reversible.
Yes, it's the equivalent of chopping wood in half, which is also a physical change. Unlike chopping wood in half, this change is completely reversible.
Unfortunately, it is not a physical/reversible change, as combustion causes chemicals to change their bonding. A simpler example than wood would be glucose (the same reaction as in respiration): C6H12O6 + 6O2 --> 6CO2 + 6H2O This reaction is not reversible.

it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.

Melting ice cubes to form water is an example of a physical change that is not reversible. Once the ice cubes have melted into water, it is not possible to reverse the process and turn the water back into ice cubes without additional processes like freezing.
