If heat is the measure of atomic kinetic energy and cold is technically the lack of heat then how can we feel radiated cold? Like if you put your hand near some ice you can feel the cold? How can the lack of something radiate?
In: Physics
It doesn’t. You’re radiating heat all of the time. Other warm objects radiate it back. An ice cube will not.
While not technically radiation, the movement of heat through air works similarly enough for this purpose. You put your warm hand near a cold countertop, your hand heats the air and the air heats the countertop, causing you to lose heat to the countertop. You “feel its cold” from afar.
