You're kidding right? Thermal inertia? LOL Heat has no mass. You must be an engineer!

I had always assumed that hot water froze before cold water because the former has a much lower concentration of dissolved gases. Cold water with it's dissolved nitrogen, oxygen and CO2, to name the main gases, behaves as a eutectic solution that exhibits a freezing point depression.

In college, I was the top student in Physical Chemistry - loved it.

I understand what you mean... let me try to be more clear.
Sure, the heat energy ITSELF has no mass, but it does "transfer" to the colder air around the water. My theory is that when you have a larger amount of heat transferring, it sets up a "current" (kind of like electrical current) and it is that process of heat transfer that has the "inertia". Make sense?

Kind of an "intuitive" approach to the problem... quite often the WRONG way to think about scientific theories!
