[題目]Two cups of coffee, one is at 100度C,and the other one is at 90度C.
If the materials of two cups are the same, and assume the emissivity of the two cups is the same.
which cup of coffee will radiate energy more, and what is the ratio of radiate energy between two cups of coffee?
[瓶頸] (寫寫自己的想法，方便大家為你解答)
我把溫度直接4次方相除,可是答案錯了,這題難道不是用R=σT^4算嗎
