Breaking off a branch of a tree is a physical change.
Yes, it is undoubtly physical itself. The cause of easy breaking eg. after chemical detoriation of its fibrous structure by molds can be chemical. The force by which it's breaking (wind, gravity) is physical however.
It is a physical change: the wood (mostly cellulose) is not changed by the breaking. However, the living cells (if any) in the branch will begin to change chemically when exposed to the air and cut off from the xylem and phloem in the rest of the tree. Eventually the cells will die and the wood will rot (chemical changes).
The Examples of Physical Changes: - hole in a paper - branch falling off tree - painting wood - breaking glass - melting ice - freezing water - melting iron The Definition of Physical Change A physical change in a substance doesn't change what the substance is. Ice melting, water evaporating (the water cycle)
grass is a physical change.
physical
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Cutting down a tree. shredding of paper as well as same of the irreversible change
it's a physical change because no new substances were formed.
Yes
burning of tree or wood is an irreversible chemical change
no it is a physical change the tree did not change into a different thing it simply changed in size
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
