Is cutting wood into 10 pieces a physical or chemical change?
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
Is cutting a diamond a physical or chemical change?
Cutting a diamond is a physical change. It involves breaking the diamond into smaller pieces through mechanical means without altering the chemical composition of the diamond itself.
Is cutting paper into tiny pieces a chemical or physical?
Cutting paper into tiny pieces is a psychical change. This is because the chemical properties of paper are left unchanged and the paper is only reduced to a fraction of its original size, which only affects its physical properties.
Is cutting up a pear a reversible change or a chemical reaction and why?
You can't glue together a divided pear,if you want it to be valuable but it is not a chemical change..why?-The reason is that a chemical change is followed by entirely new product and what you have done is to seperate the pear molecules,it is still a pear!,and it is a physical change,and you are free to ask more question,because I understand that a pear has life..
Is moving the lawn a physical or chemical change?
Mowing the lawn is a physical change because the grass is only being cut into smaller pieces, but its chemical composition remains the same. The act of cutting the grass does not alter its molecular structure.

Explain why burning of wood and cutting it into small pieces are considered as two different types of 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.
Is cutting a stack of wood from a log a chemical change?
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.
What is a physical change for a log?
The logs cellular structure becomes burnt.
