No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
Physical.
It is a physical change.
It is a physical change, because the wood is still wood but it is in a different form
no.
The cutting of wood is physical.
Do the logs change from wood to some other substance? No, so it has to be a physical change.
Physical.
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
It is a physical change.
Burning wood is a chemical change.
Cutting anything is a physical change.
It is a physical change, because the wood is still wood but it is in a different form
yes. If the matter changes completely, then that is a chemical change.
burning of wood is a chemical change as it produces heat and cutting it into small pieces is a physical change as there is a change in shape and size.
no.
The cutting of wood is physical.
Because burnning wood is using energy but breaking is using forces. When wood burns, it's not wood any more. It turns into smoke, ash, and (maybe) charcoal. When you break wood, it's still wood. When you change something into a different substance, that's a chemical change.
