Let's go over these one at a time:

Physical Properties - one is a solid and one is a gas - I think the physical properties have changed a lot... - so no to item 1.

Density - again one is a solid and one is a gas - solids are usually much more dense, heavier for a given volume than gasses - so it looks like yes to item 2

Chemical Properties - these are the atomic properties of a material - gas or solid they are still the same. so no to item 3.

Mass - Its the same amount of material so the mass would be the same. - so no to a change in mass and item 4.

Now to be fair on the density thing - if the Solid Carbon dioxide was contained in a solid container so that there could be no change in volume and it did not blow up, then the density should not have changed either - did the problem say something about remaining at atmospheric pressure also?

A change in density. Boyles law? Gas expands when heated.

Sublimation would cause a change in density.

Kid, open your textbook and READ. This isn't a place to get your homework done for you.
