The difference in temperature between and ice cube and room temperature is much less than that between a boiling kettle and room temperature. It is only when you have a tray of ice cubes and you use the back of your hand that you can sense the cold radiation.
Pictet used a sensitive air thermometer and had cooled his ice with nitric acid when he discovered cold radiation. Count Rumford, the famous physicist, could not reproduce the experiment until he was shown how in Edinburgh.
We are not discussing temperature. You began this thread dicussing heat content and radiation.
How much heat is required to produce steam from ice at 0C?
