There have to be at least a couple of Keith Gonthier ME students here who paid attention in his Fluids / Heat Transfer class that should be able to answer this question. I personally have no idea whatsoever.

39C water due to natural convection

Sir did you want that Baconator to be a combo or just the sandwich?

Regardless, my wife would simultaneously turn the downstairs AC on to cool the 39C water and turn the upstairs heat on to warm up the 1C water resulting in nothing but a massive power bill.

Same volume or same mass?
Even if you start with the same mass the 39 degree water will have a lower mass by the time it reaches 20 degrees due to increased evaporation even if it is minuscule.

The thermos is the water's mother.

4) Depends on the volume

I don't care for your punctuation. I immediately thought of sitting in a giant thermos.
