The Why behind the numbers is simple, the bittering compounds are converting and dissolving into the wort. Only the outside layer can dissolve. There is a limit to how much the wort will hold, so the process slows down as the level rises.

So at what point do the bittering compounds convert and dissolve? Is it based on temperature and thats why they are added during the boil?

Here is a great, qualitative explanation of utilization % at different boil times and gravities. It's a little technical, but not too bad.
