No, it's rifled.
Yes it could be done, but you would have to locate a smooth bore barrel to change it with. Remember smooth bore barrels are not as accurate as a rifled bore barrel.

Yes
Yes.
Smooth-bore refers to a firearm or cannon which does not have a rifled barrel (a rifled barrel is one with ridges that corkscrew down the barrel to impart a spin to the bullet)
You look down the barrel and if it is swirled it is a rifled barrel and if it is not swirled it is a smooth bore
Of coarse that's what slugs do :)
Possibly, a copper slug is made for a barrel that has riflings in it and has a straight bore, so if you try to shoot it out of a smooth bore you could mess up the choke, because the copper is solid where as a rifled slug is made of lead which is softer and is hollow in the back side with a plastic piece as a filler to allow for compression. Also if you did shoot a copper slug though a smooth bore it would not be accurate at all.
The bore of a barrel is the inside of it.
The bore is rifled so as to put a spin on the bullet. This spinning gives a greater accuracy to the bullet, especially over that of a smooth bore.
Yes and no. The yes comes from simple fact, if the projectile can move down the barrel, it can be fired. I've seen .221 Fireballs fired out of a 7TCU barrel. The no is because you cannot do it well. In effect, if you shoot a slug down a smooth bore shotgun barrel, you will have little in the way of accuracy. Slugs should be shot from a slug barrel, and shot from a smooth bore.
