Why does physical change differ from a chemical change?
As a basic example: When a block of ice melts into water, the change is physical (solid to liquid) yet the chemical contents of the ice/water remains unchanged. If a lot of salt is then dissolved in the melted water, it is still water, yet it has changed chemically into a saline (salty) solution. The added salt will increase the water's density - which could be a physical change!
Is size of an object a physical change?
The size is not a change. If there is a change in size that could be a physical change, but that depends on why its sized increased.

If the sized increased because it reacted with some other chemical, making it take up more space, that would be a chemical change that caused the size to change.
