Detailed Solution

Fixing the iron blade of a spade to a wooden handle is a physical change and fixing the iron blade of a spade to a wooden handle is a reversible change; both describe the fixing of the iron blade of a spade to a wooden handle.
When the iron blade of a spade is fixed to a wooden handle, neither the chemical property of the handle changes nor a new substance is formed. Thus, it is an example of physical change in which physical properties (such as shape and size) change, and such changes can be reversed. It is a reversible change as anytime the handle can be removed from the iron blade and fixed again.
