Yes, every chemical change must involve a physical change. When a chemical change takes place, the molecules of the chemicals involved rearrange themselves to become new types of molecules (new chemicals.)

Absolutely, but I think you mean visible or immediately noticeable changes. You might get a change in density for example, without a change in color, or volume (height, width or length). Other physical properties could also change like: boiling point, melting point or viscosity, but these wouldn't be necessarily immediately noticeable either.

...a chemical change is by definition a physical change, so yes.
