No, it's rifled.
The Thompson submachine gun, commonly known as the "Tommy Gun," did not have a smooth bore; it featured a rifled barrel. The rifling was designed to stabilize the bullets in flight, enhancing accuracy and range. While some firearms with smooth bores exist, such as shotguns, the Thompson was specifically engineered for use with .45 ACP cartridges, requiring a rifled barrel for optimal performance.
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.
