An aspect on thermal radiation : Let's be physics with 'cafe-au-lait'

Creators Domen Haruo

'Cafe-au-lait' is usually made of hot coffee and also hot milk. The liquid, mixture of coffee and milk may be cooled fiom high temperature down to the room temperature by means of radiation in natural state（conditions）. As the temperature of the hot body is increased, the radiation rate increases very rappidly, say the cooling rate becomes much larger as temperature goes higher. This time, cold milk is used insted ofthe hot one and the cold is poured into hot coffee. The comparisonis made on the following two types ofthe mixtures
