a piece of ice and a warmer thermometer are suspended in an insulated evacuated enclosure so that they are not in contact, why does thermometer reading decreases for a time?

Question

Vikas TU · Answer

The thermometer, initially at a higher temperature than the ice, will radiate at a faster rate than the ice. Eventually they have to come to the same equilibrium temperature.
