會 表面面積愈大 吸熱/散熱的速度愈快作者: chm_ming_2004 時間: 26/3/2007 06:31 PM 如果其表面顏色不同 會否改變其吸熱和散熱作者: abc666 時間: 26/3/2007 07:03 PM Dull black surfaces are good absorbers(吸收體) and good radiators(輻射體) of radiation.
Shiny surface are poor absorbers and poor radiators of heat; they reflect energy away.作者: 幻藍 時間: 26/3/2007 08:05 PM 這取決於total surface area的大少 surface area大的話absorb/release heat也會比較快作者: fish 時間: 27/3/2007 12:08 AM
該是surface area to volume ratio吧...... 樓主的問題只是set了 constant variable: material of the object Independent variable: shape dependent variable: temperature change
還有color,external factors that can spoil the equilibrium等等都會影響溫度轉變 問題根本不夠清楚......
