O3 Her perceivedcomfort is basedon both radiation and convection exchangewith the surroundings. Even though a fan does not blow cool air on her from the refrigerator, her body will radiate to the cold interior and thereby contribute to her feeling of "coolness.
All things being equal, hot water does not freezefaster than cold water. The only explanation for the observedfaster cooling is that the refrigerator might be a non-self defrost model which accumulatedan ice layer on the freezing coils. Then, when the hot water tray was placed on the ice layer, it melted and reducedthe thermal insulation betweenthe cooling coil and the ice tray.

The areafor radiation transfer is the surface areaof the food, the sameas for convection. Although there are times when the radiant heatersin the oven are substantially above the control temperaturefor the oven, a reasonableassumptionfor the radiation temperatureof the oven is probably at the control temperaturebecausethat is the temperaturemaintained by the walls which have the large areafor radiation.
A simple geometry to consider would be that of a spherehaving the samemassas the turkey, for that part of the problem. For cooking pies or other "flat" objects some other assumptionmust be made. To make an assumptionfor the flow velocity, one might visit the oven display section of a local appliancestore. In performing an analysis it is prudent to consider only a steadystateoperation of the oven, after it has reachedthe set point temperature.

Alltypes of heat transfer;conductio4 convection, and radiation vary directly with area. The surface area of thehead is much less than that of the other portion of the body and thus will lose less heat.
This may be shown experimentally by comparing expozure in cold weather wearingheavy clothing and no hat, to that wearing a heavy hat and only undergarments!
