Why do thermos flask bottles advertise 24hrs cold and 12hrs hot. Shouldn’t it be the same amount of time for temps in both directions?

I really shouldn’t be answering here, but there’s also an issue of entropy I think. the molecules of hot water are moving around quite a bit. Cold water, or even ice, the molecules aren’t moving much at all, it’s going to take more energy to get them moving around, ie heat up. And while I’m here; 32F (freezing) to 69F (room temperature) is thirty-seven degrees. 176F to 69F to is one-hundred and seven degrees.
