Regarding a smaller mass will lose heat quicker. That is the false item
A smaller SURFACE area will lose heat slower
That's why i said like a cup of water v/s a 5 gallon pail
The ratio of mass to surface area is what determines how fast the large/small mass freezes for at any given temperature of water and air the water will loose heat at the same rate PER SQUARE INCH OF SURFACE AREA .
Put that same cup of water in a narrow neck vacuum container (Thermous) and it will take a lONG time to freeze for there is very little exposed surface.
