Answer 1

Let’s assume all things are equal, and we are comparing all of the above in aluminum cans.

It’s all about specific gravity and viscosity. Seltzer is just CO2 trapped in water, whereas soda and beer contain sugar, making it more viscous this harder for the CO2 to escape. Imagine trying to swim out of a pool of water vs. trying to swim out of a pool of motor oil. Diet sodas contain salts and coloring that make them slightly more viscous than water, but even those will lose carbonation faster than a full sugar soda or beer.
