Answer 2

Answer:  

Carpenter made a chair using wood. This is usually an irreversible physical change.  

Explanation:  

This is an irreversible change since the wood that is cut down from the tree is then made into the wood which cannot be again made into a tree. It is a physical change because there is a change in the chemical nature of the particle present in the wood.

Chemical changes usually occur when the chemical composition and the chemical properties of the constituting materials change after the change. But here no such reaction takes place.
